ARM: stm32: add initial support for STM32MP13 family

This patch adds initial support of STM32MP13 microprocessor family
based on Arm Cortex-A7. New Cortex-A infrastructure (gic, timer,...)
are selected if ARCH_MULTI_V7 is defined.

ARM: stm32: use "depends on" instead of "if" after prompt

This appeared after the global fixups by commit e32465429490 ("ARM: use
"depends on" for SoC configs instead of "if" after prompt"). Fix it now.

ARM: stm32: Don't select DMA unconditionally on STM32MP157C

The patch that enabled these had no useful changelog that explains
why it is done, and it causes a build warning:

WARNING: unmet direct dependencies detected for STM32_DMA
Depends on [n]: DMADEVICES [=n] && (ARCH_STM32 [=y] || COMPILE_TEST [=y])
Selected by [y]:
- MACH_STM32MP157 [=y] && ARCH_STM32 [=y] && ARCH_MULTI_V7 [=y]

Generally, platforms should not select arbitrary drivers, so let's
just revert that change.

ARM: stm32: prepare stm32 family to welcome armv7 architecture

This patch prepares the STM32 machine for the integration of Cortex-A
based microprocessor (MPU), on top of the existing Cortex-M
microcontroller family (MCU). Since both MCUs and MPUs are sharing
common hardware blocks we can keep using ARCH_STM32 flag for most of
them. If a hardware block is specific to one family we can use either
ARM_SINGLE_ARMV7M or ARCH_MULTI_V7 flag.
