[PATCH] drm/sun4i: dw-hdmi: Deinit PHY in bind error path

[Jernej Skrabec <jernej.skrabec@gmail.com>]

sun8i_hdmi_phy_init() enables the PHY clocks and deasserts the PHY
reset. When dw_hdmi_bind() fails afterwards, the error path doesn't
undo that, so the clocks stay enabled and every further bind attempt
enables them once more.

Call sun8i_hdmi_phy_deinit() in the error path, like unbind does.
