[PATCH v2] regulator: act8865: register all regulators regardless of how many are used

[Wenyou Yang]

v2 changlog:
 1./ Rebased on the latest code of for-next branch.

As Mark pointed out, the driver should register all regulators
regardless of how many are used in the system in order to aid diagnostics.

But in the previous patch, only register the regulators that are used.
