Fix it.

Bug:
inno_hdmi_phy phy@ff430000: Pre-PLL locking failed
inno_hdmi_phy phy@ff430000: PHY: Failed to power on phy@ff430000: -110.
failed to power on phy (ret=-110)
inno_hdmi_phy phy@ff430000: Pre-PLL locking failed
inno_hdmi_phy phy@ff430000: PHY: Failed to power on phy@ff430000: -110.
failed to power on phy (ret=-110)
