Modified Files:
        syssrc/sys/arch/arm/arm: cpufunc.c cpufunc_asm_xscale.S
        syssrc/sys/arch/arm/include: cpufunc.h

Log Message:
* Give the XScale its own cpu_control() entry point; we have to flush
  the Branch Target Buffer of the BPRD bit changes.
* Enable Branch Prediction on the XScale by default.
* Don't invalidate the Branch Target Buffer explicitly. the i80200
  manual (section 5.1, Branch Target Buffer Operation) notes that
  manual software management of the BTB is unnecessary; it is flushed
  implicitly when:
     * processor resets
     * FCSE process ID is written
     * I-cache is invalidated
