[PATCH 1/2] regulator: hi655x: Constify regulators array

[PATCH 1/2] regulator: hi655x: Constify regulators array

[Axel Lin]

The regulators array should never need to be modified, make it const so
compiler can put it to .rodata.

[PATCH 2/2] regulator: hi655x: Remove ctrl_mask field from struct hi655x_regulator

[Axel Lin]

The rdev->desc->enable_mask setting is always the same as
BIT(regulator->ctrl_mask), so just use rdev->desc->enable_mask instead.
