msm_hdmi_phy_probe() enables runtime PM before enabling the PHY
resources and initializing the PLL, but failures from either operation
return without calling the matching pm_runtime_disable().
The remove path disables runtime PM, but it is not called when probe
fails. As a result, runtime PM remains enabled after an unsuccessful
probe.
Route failures after pm_runtime_enable() through a common error path
and disable runtime PM before returning.
This issue was found by manual code inspection.
