drm/msm/hdmi: Handle msm_hdmi_power_on() errors during .atomic_pre_enable()
Properly handle power up failures during .atomic_pre_enable() by
aborting the .atomic_pre_enable() to avoid accessing registers why
blocks did not bring up. Otherwise this could lead to imprecise aborts
when accessing MMIO while entire power domain is off.
