pinctrl: lynxpoint: Make use of pm_ptr()

Browse source 
Cleaning up the driver to use pm_ptr() and *_PM_OPS() macros that
make it simpler and allows the compiler to remove those functions
if built without CONFIG_PM and CONFIG_PM_SLEEP support.

The lp_gpio_resume() is also assigned to .thaw and .restore members.
This is not a problem as the function it enables input pins that
had been disabled by firmware and repetion of that doesn't change
the pin configuration, i.e. it is idempotent.
