[PATCH ARM] Fix unterminated list of options to 'set arm fallback-mode' and 'set arm force-mode'

[Matthew Gretton-Dann <matthew.gretton-dann@arm.com>]

All,

The attached patch adds a NULL entry at the end of the array of options
accepted by 'set arm fallback-mode' and 'set arm force-mode'.  Thus
ensuring GDB doesn't go wandering off trying to print garbage from
beyond the end of an array.

Can someone please review and approve?

Thanks,

Matt
