Merge tag 'u-boot-stm32-20231004' of https://source.denx.de/u-boot/custodians/u-boot-stm

STM32 MCU:
  _ alignment with kernel DT v6.5 for stm32f429 and stm32f746
  _ rework way of displaying ST logo for stm32f746-disco and stm32f769-disco

STM32 MPU:
  _ alignment with kernel DT v6.6-rc1
  _ add RNG support for stm32mp13
  _ add USB, USB boot and stm32prog command support for stm32mp13
  _ add support of USART1 clock for stm32mp1
  _ only print RAM and board code with SPL_DISPLAY_PRINT flag for
    stm32mp1
  _ rename update_sf to dh_update_sd_to_sf and add dh_update_sd_to_emmc
    for stm32mp15xx DHCOR
