msm: camera: sensor: Add pinctrl specific handling in res_mgr

Currently pinctrl is handled together regardless of pinctrl
is requested for the active/suspend state. This change adds
the per pinctrl handling when pinctrl gpio is shared among
multiple slaves. Also remove mclk specific logic as this
change will handle it at gpio/pinctrl level.
