pnp: change pnp bus pm_ops to invoke pnp driver dev_pm_ops if specified

Browse source 
pnp_bus_suspend() and pnp_bus_resume() invoke legacy pm_ops from
pnp_driver.  Changed pnp_bus_suspend() and pnp_bus_resume() to check if
pnp driver has dev_pm_ops and call.  If dev_pm_ops don't exist, then call
use legacy pm_ops.  Without this change, pnp_driver dev_pm_ops will not
get called.

In addition to the pnp driver bus pm_ops change to invoke driver
dev_pm_ops, this patch set contains changes to rtc-cmos, tpm_tis, and
apple-gmux pnp drivers to convert from legacy pm_ops to dev_pm_ops.
