For power saving during RBSC, need to vote for minimum or zero current on load for respective regulator to enter LPM mode. Add required support from audio WCD/WSA to vote accordingly during suspend/resume. Change-Id: I578195b84ba18a0b69dde3b93a3f6461efa85f7f Signed-off-by: Laxminath Kasam <lkasam@codeaurora.org>
