drm/rockchip: dw_hdmi: store rockchip_hdmi reference in phy_data object

Browse source

When using special phy handling operations we'll often need access to
the rockchip_hdmi struct.

As the chip-data that occupies the phy_data pointer initially gets
assigned to the rockchip_hdmi struct, we can now re-use this phy_data
pointer to hold the reference to the rockchip_hdmi struct and use this
reference later on.

Inspiration for this comes from meson and sunxi dw-hdmi, which are using
the same method.
