Be more forgiving of GraphicsV init failures
* Update OS_ScreenMode 11's handling of drivers which fail to initialise. If there was no previous driver, then instead of trying to restore that nonexistant driver, stick with the new one. This is mainly to help with the case where the kernel's built in modes aren't accepted by the driver, and valid modes only become available once an MDF is loaded (this can happen with early OMAP3 chip revisions, which have very tight sync & porch limits, causing 90% of the kernel's modes to be rejected). If the kernel was to revert to the "no driver" state, then loading the MDF would still leave you with no video output. * Since we can now end up in a state where a driver is selected but hasn't been programmed yet, update OS_Byte 19 to detect this (via the magic ScreenBlankDPMSState value of 255) and avoid waiting for VSync * Update RemovePages & InsertRemovePagesExit (screen DA handlers) to avoid infinite loops if the screen DA gets shrunk to zero size (was seen while attempting to complete the !Boot sequence while no driver was active) Version 6.33.
