misc: stm32: Add STM32MP1 support

Following next kernel rcc bindings, we must use a MFD
RCC driver which is able to bind both clock and reset
drivers.

We can reuse and adapt RCC MFD driver already available
for MCU SoCs (F4/F7/H7).

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

MFD stm32_rcc driver.
This also allows to add reset support to STM32F4/F7 SoCs family.
As Reset driver is not part of SPL supported drivers, don't bind it
in case of SPL to avoid that stm32_rcc_bind() returns an error.

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.
