ARM: dts: qcom: keep L1F and L3G active-only regulators always-on for Sun

Browse Source 
Configure the L1F and L3G active-only regulator to be always enabled
in high power mode (HPM).  These regulators power REFGENs and PLLs
used by the application processor itself.  Unconditional active-only
voting is needed since the software running on the application
processor won't be capable of removing L1F and L3G votes after the
application processor subsystem is power collapsed.
