[PATCH 15/38] dt-bindings: phy: mediatek,hdmi-phy: Fix clock output names for MT8195

[AngeloGioacchino Del Regno]

For all of the HDMI PHYs compatible with the one found on MT8195
the output clock has a different datasheet name and specifically
it is called "hdmi_txpll", differently from the older HDMI PHYs
which output block is called "hdmitx_dig_cts".

Add a conditional to allow the new clock output name on all of the
HDMI PHY IPs that are perfectly compatible with MT8195.
