Subject: [PATCH v2] regulator: tps65910: Simplify setting enable_mask for
 regulators

BBCH_BBCHEN_MASK is equivalent to TPS65910_SUPPLY_STATE_ENABLED.
So all regulators have the same enable_mask setting.

BBCH_BBCHEN_MASK and BBCH_BBCHEN_SHIFT are not used now, remove them.

Signed-off-by: Axel Lin <axel.lin@...ics.com>

v2: (Base on Markus' comment) remove unused BBCH_BBCHEN_* in tps65910.h.
