Subject: [PATCH v2 5/6] drm/sun4i: sun8i-hdmi-phy: Separate A83T and H3 PHY ops
Since the driver already needs to support multiple sets of ops, we can
drop the mid-layer used by the A83T and H3 PHYs. They share only a small
amount of code; factor this out as sun8i_hdmi_phy_set_polarity.
For clarity, this commit keeps the existing function order.
