Merge tag 'u-boot-at91-2022.01-a' of https://source.denx.de/u-boot/custodians/u-boot-at91 into next

First set of u-boot-at91 features for the 2022.01 cycle:

This feature set includes : the support for CPU driver for arm926
(sam9x60 device); changes required for OP-TEE boot for sama5d2_xplained
and sama5d27_som1_ek boards; QSPI boot configuration for sama5d2_icp;
starting to remove old Kconfig unused symbols from config_whitelist.txt
(work will take more time); also small fixes and updates in mach, DT,
configs, etc.
