This clarifies which callers must be updated to complete the DM_GPIO
conversion.
The only remaining caller of name_to_gpio in generic code is inside the
!DM_GPIO block in cmd/gpio.c. DM_GPIO is always selected on sunxi, so
that code cannot be reached. And after this commit, there are only two
remaining implementations of name_to_gpio.

As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various
files that include it.
Some files did not contain any GPIO code at all, so this header was
completely unused.
A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.
The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the
right header to include once the DM_GPIO migration is complete and
GPIO_EXTRA_HEADER is no longer needed.

Only one board, Yones Toptech BD1078, actually uses a non-default MMC
pinmux. All other uses of these symbols select the default value or an
invalid value. To simplify things, remove support for the unused pinmux
options, and convert the remaining option to a Boolean.
This allows the pinmux to be chosen by the preprocessor, instead of
having the code parse a string at runtime (for a build-time option!).
Not only does this reduce code size, but it also allows this Kconfig
option to be used in a table-driven DM pinctrl driver.

Current CP1 pinctrl that is set on the Puzzle M801 is incorrect.
CP1 pins are only used for the SMI bus and the MSS I2C, all other
pins are just GPIO-s.
Due to this being set completely wrong, the pinctrl was actually
ended up being hardcoded in the board_early_init_f() step so that
SMI would work.
That is obviously not the right thing to do, so convert the register
hex values that were being written to individual pin modes and set it
in the DTS.
Add the SMI pins to the CP1 MDIO node as otherwise CP1 pinctrl does
not get probed without an consumer.

This code is trying to parse PCIe config space of PCIe card connected on
the other end of link and then is trying to force 5.0 GT/s speed via Target
Link Speed bits in PCIe Root Port Link Control 2 Register on the local part
of link if it sees that card supports 5.0 GT/s via Max Link Speed bits in
Link Capabilities Register.
The code is incorrect for more reasons:
- Accessing config space of an endpoint card cannot be done immediately.
If the PCIe link is not up, reading vendor/device ID registers will
return all ones.
- Parsing is incomplete, so it can cause issues even for working cards.
Moreover there is no need to force speed to 5.0 GT/s via Target Link Speed
bits on PCIe Root Port Link Control 2 Register. Hardware changes speed from
2.5 GT/s to 5.0 GT/s autonomously when it is supported.
Most importantly, this code does not change link speed at all, since
because after updating Target Link Speed bits on PCIe Root Port Link
Control 2 Register, it is required to retrain the link, and the code for
that is completely missing.
The code was probably needed for making buggy endpoint cards work. Such a
workaround, though, should be implemented via PCIe subsystem (via quirks,
for example), as buggy cards could also affect other PCIe controllers.
Note that this code is fully unrelated to a38x SerDes code and really
should not have been included in SerDes initialization. Usage of magic
constants without names and comments made this SerDes code hard to read and
understand.
Remove this PCIe application code from low level SerDes code. As this code
is configuring only 5.0 GT/s part, in the worst case, it could leave buggy
cards at the initial speed of 2.5 GT/s (if somehow before this change they
could have been "upgraded" to 5.0 GT/s speed even with missing link
retraining). Compliant cards which just need longer initialization should
work better after this change.

PCI device ID is part of the PCIe controller SoC / revision. For Root

If there is some issue with this device ID, it should be set / updated by
PCIe controller driver (pci_mvebu.c), as this register resides in address
space of the controller. It shouldn't be done in SerDes initialization

In the worst case (a specific board for example) it could be done via

write to wdog CNT register in 16 bus clocks window, if miss the
window, the write will cause violation in wdog and reset the chip.
Current u-boot code is using writel() function which has a DMB
barrier to order the memory access. The DMB between two words write
may introduce some delay in certain circumstance, causing the wdog
reset due to 16 bus clock window requirement.
Also, WDOG1 might have been enabled already depending on FUSE hence
we need to be as close as possible to its reconfiguration timing
