fix-suspend-backlight-timing-pm-debug.patch
This patch improves the smoothness of suspend and resume action.
Taking out CONFIG_PM_DEBUG allows much more rapid resume (the low level
serial traffic appears to be synchronous)
Added a platform callback in jbt driver and support in pcf50633 so we
can defer bringing up the backlight until the LCM is able to process
video again (which must happen after the glamo is up and producing
video beacuse the LCM is hooked to glamo SPI)
GTA01 should not be affected by all this as the callback will default
to null and it is on pcf50606
