msm: board-8960: Configure PM8921 SMPS 4 to use auto mode
Change the RPM regulator configuration data for PM8921 SMPS 4 on
MSM8960 so that RPM requests are made with force mode = auto
instead of force mode = none. Auto mode allows the regulator to
switch automatically between HPM and LPM in hardware based on
real time current load.
