libpayload: keyboard: Ignore special keys
Some special keys emit a prefix scan code 0xE0. We will ignore all
these except for the power button, F12 and cursor keys on drallion.
Media key mapping is set in depthcharge and will be sent to libpayload
keyboard driver. Whichever board requires this change will update its own
media key mapping.
BUG:b:139511038
TEST=boot in recovery mode, press F12 to go to diagnostic mode and power
button to confirm. Also in recovery mode left arrow, right arrow, up arrow,
down arrow changes the language on the firmware screen.
