Pinconfig nodes normally bind recursively with PINCTRL_FULL and

any node marked with e.g. bootph-all will not bind unless its parent is
also marked for pre-reloc.
group1 {
pinconf1 {

This cause the following warning message to be shown during U-Boot

This adds the new Kconfig stanza, using the two newly introduced symbols
for the new SoC generation and pincontroller. It also adds the new symbols
to the relavent code places, to set all the hardcoded bits directly.
We need one DT override:
The ARM core version of the DT specifies the CPUX watchdog as

For Allwinner boards we still need to deal with non-DM GPIO in the SPL,
but this should become the exception, not the rule.
Make this more obvious by removing the definition of GPIO_EXTRA_HEADER,

So far every Allwinner SoC used the same basic pincontroller/GPIO
register frame, and just differed by the number of implemented banks and
pins, plus some special functionality from time to time. However the D1
and successors use a slightly different pinctrl register layout.
Use that opportunity to drop "struct sunxi_gpio", that described that
MMIO frame in a C struct. That approach is somewhat frowned upon in the
Linux world and rarely used there, though still popular with U-Boot.
Switching from a C struct to a "base address plus offset" approach allows
to switch between the two models more dynamically, without reverting to
preprocessor macros and #ifdef's.
Model the pinctrl MMIO register frame in the usual "base address +
offset" way, and replace a hard-to-parse CPP macro with a more readable
static function.
All the users get converted over. There are no functional changes at
this point, it just prepares the stages for the D1 and friends.
