Merge tag 'u-boot-at91-2022.07-a' of https://source.denx.de/u-boot/custodians/u-boot-at91 into next
First set of u-boot-at91 features for the 2022.07 cycle:
This feature set includes the new driver for the Atmel TCB timer,
alignment in DT for sama7g5 and sama7g5ek board, one Kconfig conversion
for external reset, and the usage of Galois tables from ROM for sama5d2
device.
