msm: camera: common: Detach pinctrl state operation

Telusuri Sumber 
Currently pinctrl state update operation is integrated
with platform resource operation. This can create unwanted
transition of pinctrl which can stay in suspend state.
This change detach and separate out the pinctrl entries
with index passed from devicetree. Pinctrl select
state operation is detach from platform enable/disable
operation to operate from device directly only for better
control with respect to operation.
