feat(stm32mp1): remove unsupported features on STM32MP13

Browse source 
* GPIO: On STM32MP13, there are no banks GPIOJ, GPIOK and GPIOZ.
* STM32MP13 is a single Cortex-A7 CPU: remove reset from MPU1
  and reset from MCU traces
* There is no MCU on STM32MP13. Put MCU security management
  under STM32MP15 flag.
* The authentication feature is not supported yet on STM32MP13,
  put the code under SPM32MP15 flag.
* On STM32MP13, the monotonic counter is managed in ROM code, keep
  the monotonic counter update just for STM32MP15.
* SYSCFG: put registers not present on STM32MP13 under STM32MP15
  flag, as the code that manages them.
* PMIC: use ldo3 during DDR configuration only for STM32MP15
* Reset UART pins on USB boot is no more required.
