[PATCH] phy: freescale: fsl-samsung-hdmi: Balance runtime PM operations

[Fabio Estevam]

From: Fabio Estevam <festevam at nabladev.com>

fsl_samsung_hdmi_phy_probe() enables runtime PM, but the remove
callback does not disable it. Unbinding and rebinding the device
therefore results in the following warning on reprobe:

Unbalanced pm_runtime_enable!

Disable runtime PM after removing the clock provider.

Also undo the runtime PM operations when phy_clk_register() fails.
Otherwise, a failed probe leaves runtime PM enabled and the usage
counter incremented.
