This commit fixes a bug with the declaration of the Kconfig option
MEMC_STM32.
The option is defined in two files:
- `drivers/memc/Kconfig.stm32`, wich depends on
- `MEMC`
- `DT_HAS_ST_STM32_FMC_ENABLED`
-`soc/st/stm32/Kconfig.defconfig`, wich depends on
- `MEMC`
- `SOC_FAMILY_STM32`
So, if you have `CONFIG_MEMC=y` in your Kconfig options and you are on a
STM32 SoC, `CONFIG_MEMC_STM32` will be enabled, even if there is no
STM32 FMC enabled.
This Kconfig option causes the driver for the STM32 FMC to be compiled,
regardless of the presence of an enabled node for the FMC.
However, the driver fails to compile if there is no FMC node in the
devicetree. So, if you compile a project with `CONFIG_MEMC=y` on a board
with an STM32 SoC and no enabled FMC, the build will fail.
This commit deletes the Kconfig declaration in the `Kconfig.defconfig`,
as it isn't useful and is the one provoking the bug.
It also add in the `Kconfig.stm32` the compatible `st,stm32h7-fmc`, wich
use the same driver and so need to be enabled by the same Kconfig
option.

Update memc drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

According to Kconfig guidelines, boolean prompts must not start with
"Enable...". The following command has been used to automate the changes
in this patch:
sed -i "s/bool \"[Ee]nables\? \(\w\)/bool \"\U\1/g" **/Kconfig*

Default the option MEMC_STM32 to "y" when the device node is defined and
enabled, so that the driver is selected automatically when the board
supports it and MEMC is enabled.
Remove the default conditional on serise as it's redundant with the one
in soc/arm/st_stm32/common/Kconfig.defconfig.series.

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.
