ARM: dts: msm: add pin control regulators for WLAN and BT on msmcobalt 



Initialize PMCOBALT regulators SMPS 7 and LDO 5 to use HW_EN0 pin
control to force high power mode. Whenever HW_EN0 is driven high these
regulators will be forced into high power mode.

HW_EN0 is driven high whenever WLAN is transmitting or receiving, thereby
reducing power when it is not active.

Initialize PMCOBALT regulators SMPS 3 and SMPS 5 to use HW_EN2 pin
control to force high power mode. Whenever HW_EN2 is driven high these
regulators will be forced into high power mode.

Add pin control regulator devices for PMCOBALT regulators LDO 7, LDO
17, and LDO 25. When any of these pin control regulators are enabled by
software their output will be physically enabled whenever HW_EN2 is driven
high. When disabled HW_EN2 is ignored.

HW_EN2 is driven high whenever BT is transmitting or receiving, thereby
reducing power when it is not active.
