The stm32 platform started out as a Cortex-M based microcontoller
platform in 2007, with a few of the older products gaining Linux kernel
support in 2016. These days, the only relevant chips for Linux are the
stm32mp1 (Cortex-A7) and stm32mp2 (Cortex-A35) product lines, with the
microcontrollers running smaller RTOSs on new products.

The microcontrollers were marked as deprecated in the linux-7.3LTS
release, which will remain supported for a few more years and
is expected to be sufficient for any of the remaining original users.

Remove the MCU support now, leaving only the stm32mp SoCs in the platform.
