[PATCH 0/2] drm: tda998x: Fix a couple of problems

1)
The HDMI registers of the tda998x chips are accessed by pages.
As these HDMI registers may be accessed from different tasks
(video, irq/workqueue, and soon audio), the page register setting
must be protected.

2)
On HDMI reconnect (cable plug-in), the EDID is read too early and
this raises a EDID read timeout. Delaying a bit the connect event
fixes the problem.
