keyboard_scan: Add option to not handle special key combinations
On some boards, the special alt-volup-r/h combinations do not make
a lot of sense, so we can just not process them and save a little
bit of code space.
BRANCH=none
BUG=b:37422577
TEST=Flash hammer, alt-volup-r/h does not do anything special
TEST=make newsizes shows we save 124 bytes in hammer RW.
