Improve Reset_IRQ_Handler
Jeffrey Lee authored 
Detail:
  s/HAL - Reset_IRQ_Handler now uses HAL_IRQSource to determine the cause of the interrupt, using that value to work out which IIC bus (if any) generated the IRQ. If it's unrecognised it passes it to HAL_KbdScanInterrupt, and if that fails to do anything it'll disable the IRQ.
  This aims to fix the spurious "No XStart!" debug spam that the OMAP IIC drivers produce when the keyboard scan is running, and to fix the potential IIC breakage that could occur by the IIC code trying to clear the non-existant interrupt.
  Note that behaviour of HAL_KbdScanInterrupt has now been changed; it now accepts the device number in a1, and is expected to return either -1 (if the interrupt was handled) or the device number given as input (if the interrupt wasn't handled, e.g. not from a device managed by the keyboard scan code).
