Add OF match entries and quirks for Renesas RCar Gen3 controllers

one and in used both in Socionext and Renesas chips.

Check if the OF match has any associated data and if so, use those
data as the controller quirks, otherwise fallback to the old method
of reading the controller version register to figure out the quirks.
This allows us to supply controller quirks on controllers which ie.
do not have version register.

The Renesas RCar Gen3 contains the same controller, originally
Matsushita, yet the register addresses are shifted by 1 to the
left. The whole controller is also 64bit, including the data
FIFOs and RSP registers. This patch adds support for handling
the register IO by shifting the register offset by 1 in the IO
accessor functions.

This patch adds the support of reset and clock control
block (rcc) found on STM32 SoCs.
This driver is similar to a MFD linux driver.
This driver supports currently STM32H7 only.
STM32F4 and STM32F7 will be migrated to this rcc MFD driver
in the future to uniformize all STM32 SoCs already upstreamed.

This driver is adapted from linux drivers/reset/reset-stm32.c
It's compatible with STM32 F4/F7/H7 SoCs.
This driver doesn't implement .of_match as it's binded
by MFD RCC driver.
To add support for each SoC family, a SoC's specific
include/dt-binfings/mfd/stm32xx-rcc.h file must be added.
This patch only includes stm32h7-rcc.h dedicated for STM32H7 SoCs.
Other SoCs support will be added in the future.

With the new 32/64bit-aware dtoc, the type of reg is fdt64_t and the
OF_PLATDATA structure layout changes. This adjusts the DMC driver for
the RK3368 to track these changes.
For the time being (i.e. until regmap_init_mem_platdata works for the
64bit case), we won't use regmap_init_mem_platdata here and simply
access of_plat.reg[] directly.

The generic ehci-driver (ehci-generic.c) will try to enable the clocks
listed in the DTSI. If this fails (e.g. due to clk_enable not being
implemented in a driver and -ENOSYS being returned by the clk-uclass),
the driver will bail our and print an error message.
This implements a minimal clk_enable for the RK3399 and supports the
clocks mandatory for the EHCI controllers; as these are enabled by
default we simply return success.

Version-changes: 2
- use the dev_read_addr_ptr function in rk_gpio.c
To make the Rockchip DM timer driver useful for the timing of
bootstages, we need a few enhancements:
- This implements timer_get_boot_us.
- This avoids reinitialising the timer, if it has already been
set up (e.g. by our TPL and SPL stages). Now, we have a single
timebase ticking from TPL through the full U-Boot.
- This adds support for reading the timer even before the
device-model is ready: we find the timer via /chosen/tick-timer,
then read its address and clock-frequency, and finally read the
timeval directly).
