regulator: Fixes for v5.3

Browse Source 
This is obviouly very late, containing three small and simple
 driver specific fixes.  The main one is the TWL fix, this fixes
 issues with cpufreq on the PMICs used with BeagleBoard generation
 OMAP SoCs which had been broken due to changes in the generic OPP
 code exposing a bug in the regulator driver for these devices
 causing them to think that OPPs weren't supported on the system.
 
 Sorry about sending this so late, I hadn't registered that the
 TWL issue manifested in cpufreq.
