Series ARM: at91: add cpu idle and cpufreq opps for sama7g5 | expand

Commit Message

Claudiu Beznea Jan. 13, 2022, 2:48 p.m. UTC 
Set regulator voltages for standby state to avoid wrong behavior of
system while in standby. The CPU voltage has been chosen as being the
one corresponding to OPP=600MHz. Next commit will set the 600MHz OPP
as the suspend OPP.
