msm: board-8930: Configure PM8038 SMPS regulators to use auto mode and LPM

Browse Source 
Change the RPM regulator configuration data for PM8038 SMPS
regulators on MSM8930 so that active set RPM requests are made
with force mode = auto instead of force mode = none. Also change
force mode to LPM for sleep set requests.

Auto mode allows a regulator to switch automatically between
HPM and LPM in hardware based on real-time current load. Forced
LPM is utilized in the sleep set because it allows for
additional power savings beyond auto mode.
