gma-display_probing: Enable panel power early

Before probing the internal panels EDID, we have to wait for the panel
power up delay. To use this time, we enable the panel power before pro-
bing any port and can probe external ports during the delay. On a T420
this saves about 5ms without an external display connected and 15ms
with.
