armv4_5: support weirdo ARMv6 secure monitor mode

On the ARM PB1176JZF-S the system comes up in secure monitor
mode after reset. However the modebits in CPSR form the value
28 (0x1c) and CPSR is 0x800001dc deeming it UNRECOGNIZED.
Define this mode to be synonymous to mode 22 (MON) and things
start to work like a charm.
