As we now support both the stm32mp157a-dk1 and stm32mp157c-dk2 with
the same barebox image, we should call the board stm32mp15xx-dkx
instead. That's also how the upstream DTSI is named.

Board drivers are now the way to go. Migrate the STM32 boards to use it,
to encourage future copy-pasting in following suit.
As the board now supports both DK2 and DK1, rename the prefix to dkx_.
dk1 specifics follow in a separate commit.

These includes are no longer needed because we don't need to hard code
memory size in board code anymore for the STM32MP. Drop them.

The full "STMicroelectronics STM32MP157C-DK2 Discovery Board" is a tad
too long. Abbreviate it to STM32MP157C-DK2 instead.

There's new infrastructure for runtime determining RAM size. Use it so
we don't need to hard code it in PBL and board code.
Because this new infrastructure has some nested function calls, my
arm-v7a-linux-gnueabihf-gcc 9.2.1 (OSELAS.Toolchain-2019.09.0)
spills to the stack. Add stm32mp_cpu_lowlevel_init, which also sets up
a stack after barebox end so this works.
Lastly, there's no upstream device tree node for the DDR controller.
Add one in the barebox device tree, so we don't have to hardcode the
DDRCTRL address into non-pbl code that's run everywhere.

Now with the SD/MMC controller supported, lets add a bbu handler, so we
can use it to update the second stage boot loader partition.

dk2_postcore_init is not at postcore init level like the name would
suggest, but at mem init level. Rename it accordingly.

This adds initial STMicroelectronics MP1 support along with support
for the DK2 devel board. Only very basic support:
- UART
- SDRAM memory base/size
- No 1st stage support
