armv4_5: fix segmentation fault in command 'arm reg'
Commit fed713104904 ("armv4_5: support weirdo ARMv6 secure monitor
mode") introduces the secure mode 28 of ARMv6 as a synonymous of
mode 22 (MON), but does not add it in the switch/case in command
'arm reg'.
When command 'arm reg' scans the array arm_mode_data[] on targets
without secure modes, it does not detect the new secure mode as
not supported by the architecture, thus triggers a segmentation
fault when it try to read the register's value from unallocated
memory.
Issue detected with target arm926ejs.
Add the new mode in the switch/case and treat it as the mode MON.
