drm/meson: dw-hdmi: power up phy on device init
[ Upstream commit 04703bfd ] The phy is not in a useful state right after init. It will become useful, including for auxiliary function such as CEC or ARC, after the first mode is set. This is a problem on systems where the display is using another interface like DSI or CVBS. This change refactor the init and mode change callback to power up the PHY on init and leave only what is necessary for mode changes in the related function. This is enough to fix CEC operation when HDMI display is not enabled.
