[H5 dev] updated 1.3GHz fixed voltage (1.3v) overclock overlay for ke…
Browse files Browse the repository at this point in the history 
…rnel 4.19.y

the new cpu opp table in 4.19 now supports frequencies up to 1.368GHz, so this change
updates the 1.3GHz overclock overlay as appropriate.  overlay name has been changed
to "cpu-clock-1.3GHz-1.3v" as this overlay is only needed for boards that provide a
fixed-voltage GPIO regulator/switcher that operate at 1.1v/1.3v.
