feature-arm-thumb.inc: drop ARM -vs- thumb comments
Comments are old and specific to thumb1. Since oe-core CPU tuning files aren't really the right place to fully document ARM -vs- thumb, drop the comments instead of trying to update them. (From OE-Core rev: 06225600d4d3041da0d28c79058e5b8ceb4874bf) Signed-off-by: Andre McCurdy <armccurdy@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

5# but requires more instructions (140% for 70% smaller code) so may be
