277efd30cf ARM: shmobile: Check r8a7791 MD21 at SMP boot 
On r8a7791 the hardware boot mode bit MD21 indicates if hardware
debug mode is enabled or not. In case hardware debug mode is enabled
print a warning and refrain from booting secondary CPU cores.

Without this patch Koelsch with SW8-4 set to OFF will hang at SMP boot.

687c27b070 ARM: shmobile: r8a7791 SMP support 
Tie in the APMU SMP code on r8a7791. When used together
with the secondary CPU device node and smp_ops in the
board specific code then this will allow use of the
two Cortex-A15 cores in the r8a7791 SoC.
