[PATCH v2 4/4] phy: freescale: fsl-samsung-hdmi: Disable APB clock on resume failure

[Can Peng]

fsl_samsung_hdmi_phy_resume() enables apbclk and then reprograms the PHY
when a previous clock configuration is available. If the hardware
configuration fails, the function returns the error with apbclk still
enabled.

Disable apbclk on the failure path so the clock enable count remains
balanced.
