[PATCH] ARM: stm32mp: Make ARCH_STM32MP13 and ARCH_STM32MP157 selectable

[Jonas Rebmann]

ARCH_STM32MP13 and ARCH_STM32MP157 are automatically selected if a
dependent machine is selected. However, without any machine selected,
CONFIG_ARCH_STM32MP still enables build of the
barebox-stm32mp-generic.img image, which, provided a dtb, is functional
without requiring further board specific code.

In this case ARCH_STM32MP13 and/or ARCH_STM32MP157 need to be explicitly
enabled for the SoC to be fully functional (e.g. clocks).

Agreed, See d92583d5bab2 ("ARM: cpu: allow selecting CPU_V7/CPU_V8
directly").
