Merge tag 'u-boot-at91-2022.10-a' of https://source.denx.de/u-boot/custodians/u-boot-at91 into next

First set of u-boot-at91 features for the 2022.10 cycle:

This feature set includes mostly fixes and alignments: DT alignment with
Linux for sama7g5, removal of invalid eeprom compatibles, removal of
extra debug_uart_init calls for all at91 boards, support for pio4 driver
pioE bank, and other minor fixes and enhancements for sam9x60 and
sama5d2_icp boards.
