serial: 8250_omap: Fix probe and remove for PM runtime
[ Upstream commit 4e0f5cc65098ea32a1e77baae74215b9bd5276b1 ]
Otherwise the interconnect related code implementing PM runtime will
produce these errors on a failed probe:
omap_uart 48066000.serial: omap_device: omap_device_enable() called from invalid state 1
omap_uart 48066000.serial: use pm_runtime_put_sync_suspend() in driver?
Note that we now also need to check for priv in omap8250_runtime_suspend()
as it has not yet been registered if probe fails. And we need to use
pm_runtime_put_sync() to properly idle the device like we already do
in omap8250_remove().
