video: msm: Call complete_all if vsync times out for LCDC

 * If vsync times out, we need to call complete_all otherwise the wait
   count goes to zero and we are stuck forever.
 * Should hopefully fix the hangs and crashes.

ariesve: Some changes to gp4 voltage regulators to fix touchscreen voltage

These changes allow to prevent these errors when setting touchscreen voltage:
<3>[    0.063964] ldo10: requested voltage range [1800000, 1800000] does not fit within previously voted range: [2600000, 2600000]
<3>[    0.064086] oliver_tsp_ldo_on: vreg LDO2 set level failed (-22)

The touchscreen after getting this error uses the wrong voltage of
2600000 uV instead of 18000000 uV.

The regulator's core has been changed and the voltage range that doesn't
fit the previously set voltage range is not allowed, so we need to correct
the other occurrences where gp4 regulator has been registered.
