twl-regulator: Define critical regulators as always_on
Defines VIO, VDD1, VDD2, VPLL1 and VINT* regulators as always_on by default since they are critical to TWL and its master's functionality and should be on in all cases where RegFW is used Signed-off-by: Juha Keski-Saari <ext-juha.1.keski-saari@nokia.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
