[PATCH] regulator: twl: Regulator mode should not depend on regulator enabled state

[Ivaylo Dimitrov]

When machine constraints are applied, regulator framework first sets
initial mode (if any) and then enables the regulator if needed. The current
code in twl4030reg_set_mode always checks if the regulator is enabled
before applying the mode. That results in -EACCES error returned for
"always-on" regulators which have "initial-mode" set in the board DTS. Fix
that by removing the unneeded check.
