Clean up remaining kernel hacks
Jeffrey Lee authored 
Detail:
  Docs/RPiNotes - Deleted, contents no longer relevant
  s/HAL, s/Kernel, s/vdu/vduswis, s/pmf/key - Cleaned up debug code
  s/NewIRQs - No need to piggy back on timer 0 IRQ to generate a fake VSync; PushModeInfo already claims/releases TickerV as appropriate if video driver doesn't provide a VSync IRQ.
  s/NewReset - Re-enable LookForHALRTC call, the stack imbalance bug was fixed before the Pi changes were merged in
  s/vdu/vducursoft - Streamline PostWrchCursor a bit by only preserving R14 around RestorePointer if the software pointer is in use
  s/vdu/vdudriver - Amend ModeChangeSub improvements to ensure old external framestore handling logic is used if driver doesn't support framestore growth/realloc
Admin:
  Tested on Raspberry Pi with high processor vectors
  Kernel now looks to be in a good state for merging back into HAL branch
  Note - Software mouse pointer support in vducursoft only checks HALVideoFeatures, so doesn't take into account the capabilities of any GraphicsV driver that may be in use.
