google/scarlet: Add initialization sequence for Innolux P097PFG panel
Innolux didn't deliver a working init sequence yet for devices without
OTP programming. The sequence in this change has been derived from a
register dump of a mostly working panel with OTP. It is not meant to
be final, but to make devices with unprogrammed OTP work, while Innolux
is figuring out a proper sequence. There is a known issue with an
artifact line in the lower third of the display.
