[PATCH 15/21] arm: stm32mp: disable console for UART serial boot

[Patrice Chotard]

For UART serial boot, the console need to be deactivated to avoid issue
with tools STM32CubeProgrammer.

This patch adds also the missing dependency for CMD_STM32PROG_SERIAL,
to allow the silent and disable console. This avoid to add is on
board level for STM32MP15 (with TARGET_ST_STM32MP15X or
TARGET_ST_STM32MP13X)
