Merge tag 'u-boot-atmel-2021.01-a' of https://gitlab.denx.de/u-boot/custodians/u-boot-atmel into next
First set of u-boot-atmel features for 2021.01 cycle:
This feature set includes a new CPU driver for at91 family, new driver
for PIT64B hardware timer, support for new at91 family SoC named sama7g5
which adds: clock support, including conversion of the clock tree to
CCF; SoC support in mach-at91, pinctrl and mmc drivers update. The
