Oleksandr Tymoshenko 78b5418242 [qemu] Fix VERSATILEPB kernel boot in QEMU broken by r300968
QEMU does not implement hardware debug registers so when
dbg_monitor_is_enabled is called kernel receives "invalid instruction"
exception. QEMU implements only DIDR register and on read returns all
zeroes to indicate that it doesn't support other registers. Real
hardware has Version bits set.
