drm/i915: Initialize panel timing registers if VBIOS did not
The time between start of the pixel clock and backlight enable is a basic
panel timing constraint. If the Panel Power On/Off registers are found
to be 0, assume we are booting without VBIOS initialization and set these
registers to something reasonable.

[ickle: rearranged into a separate function to distinguish its role from
simply parsing the VBIOS tables.]
