mkbp: Consider max_code requested when returning button/key codes
Currently, button codes are returned without considering the max codes
requested by the caller and key code handling checks for overflow
after adding a key. Fix that by creating a common function for adding
key/button codes that checks total against max_codes. Also, update
changed to be 0 or 1 only since we only use that as a boolean flag.
BUG=None
BRANCH=None
TEST=Verified that buttons still work on poppy.
