    Detail:
      Makefile - add s.PRCM to objects
      s/Boot - Call PRCM_SetClocks during HAL_Init. Added (disabled) debugging code.
      s/Interrupts - Updated HAL_IRQSource, HAL_FIQSource to query ARM interrupt state instead of relying on INTC alone to detect whether an interrupt is firing or not.
      s/PRCM - Code to measure system clock frequency, store it for HAL purposes, and notify the OMAP of the frequency in order to ensure correct operation.
      s/Timers - Use measured system clock frequency as the timer frequency instead of hard-coded value. Return correct values from HAL_TimerPeriod.
      s/Top - Added (disabled) debugging code. Updated ARM initialisation to use correct cache cleaning procedure.
      s/Video - Further minor work towards completing video driver.
      hdr/CoPro15ops - Deprecate ARM_flush_* macros
      hdr/PRCM - Add more register addresses
      hdr/StaticWS - Add entried for PowerMan & 32K timer logical addresses, system clock speed
      hdr/Timers - remove incorrect, hard-coded timer frequency
      hdr/omap3530 - remove unused FlashCheck global, add DebugChar macro

      Tested with HALTester and the RISC OS kernel using qemu-omap3.
      Tested with HALTester on a rev. B6 beagleboard.
