pnp: change pnp bus pm_ops to invoke pnp driver dev_pm_ops if specified
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. This patch (of 4): 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.
