Kumar Gala b275fec8c4 soc: stm32: convert to use DEVICE_DT_GET for clocks
Convert from device_get_binding to DEVICE_DT_GET.  In doing this we
no longer need the label in the devicetree node so we remove that.

Removed all __ASSERT_NO_MSG(clk) since we'll get a build error if
DEVICE_DT_GET cant be satisfied, and the clock control api's will
handle reporting if the device_is_ready.

Gerard Marull-Paretas e671d363b8 drivers: memc: stm32: initial support for stm32 FMC
This commit adds a new driver category for memory controller
peripherals. There is no API involved for now, as it has not been found
necessary for first implementation.

STM32 Flexible Memory Controller (FMC) is the only controller supported
for now. This peripheral allows to access multiple types of external
memories, e.g. SDRAM, NAND, NOR Flash...

The initial implementation adds support for the SDRAM controller only.
The HAL API is used, so the implementation should be portable to other
STM32 series. It has only been tested on H7 series, so for now it can
only be enabled when working on H7.

Linker facilities have also been added in order to allow applications to
easily define a variable in SDRAM.
