IPQ4019 has more networking related resets that will be required for future
wired networking support, so lets add them.
This syncs the driver with Linux.

A lot of the features in here are only relevant when running
multi-threaded with interrupts. Drop everything except what we need to
run single-threaded with a single TCS (which is all the rpmh-rsc
framework in U-Boot supports).
Keep rpmh_write_async() for simplicity and make it wrap the regular
rpmh_write().

Minor adjustments to fix building with U-Boot and work correctly as a

Since U-Boot is single threaded, we can avoid most of the complexity
that comes with handling more than one in-flight TCS. Drop all the rpmh

response on each TCS.

Keep the header pointer in the .data section so we don't initialize it
again after relocation, adjust cmd_db_get_header() to work with the
U-Boot API, and skip validating the header since all cmd-db users are
children of the rpmh-rsc and those children will only probe if cmd-db
initializes successfully.

Integrate cmd-db into the U-Boot driver model.
This is just a wrapper around an in-memory database, so we just need to
get the address and validate that cmd-db is there.
Since cmd_db_header will be stored in the .data section we can skip
bind if it's already set.

Add True Random Number Generator (TRNG) driver for Exynos chips. This
implementation is heavily based on Linux kernel's counterpart [1]. It
also follows upstream dt-bindings [2].
TRNG block is usually a part of SSS (Security Sub System) IP-core on
Exynos chips. Because SSS access on Exynos850 is protected by TZPC
(TrustZone Protection Control), it's not possible to read/write TRNG
registers from U-Boot, as it's running in EL1 mode. Instead, the
corresponding SMC calls should be used to make the secure software
running in EL3 mode access it for us. Those SMC calls are handled by
LDFW (Loadable Firmware), which has to be loaded first. For example, for
E850-96 board it's done in its board_init(), so by the time RNG
capabilities are needed the LDFW should be already loaded and TRNG
should be functional.

- Conversions to DM_I2C and DM_SERIAL.
- Support for I2C3 and PWM1 for the imx6q clock driver.
- Improvements for udoo-neo
- Describe the i.MX93 CPU clocks in the devicetree to fix CPU clock printing
- Fix for SPI and NANC clk-imx8mn clock driver
Enabling CONFIG_CMD_PWM, and consequently CONFIG_DM_PWM, causes the pwm
command to fail due to a missing clock.
=> pwm enable 0 0
Enable clock-controller@20c4000 failed
Failed to enable per_clk
pwm: '0' not found
Command 'pwm' failed: Error -2
Note that it is trivial to also add the clocks for PWM2, PWM3, and PWM4.
However, I only tested PWM1 and thus only added the clock for that
signal.

Commit 727fa4539ca2 ("clk: Add support for I2C clocks on NXP's imx6q SoC
which use CCF") added I2C clocks for I2C1 and I2C2, but not I2C3.
Consequently, devices using I2C3 fail after enabling CONFIG_CLK_IMX6Q
and thus CONFIG_CLK. Therefore, this commit adds the last I2C clock.

The osc_24m is the clock-output-name and not the one that
is used as internal name reference from the strcmp. The clock
that use osc_24m, will not be able to reparent it as they should.
We need anyway register the osc_24m clock fixed factor in the clock
tree.
