libpayload: classify all keyboards
Depthcharge uses the keyboard type to help determine whether
it can trust the keyboard for security-sensitive confirmations.
Currently it trusts anything except usb, but now there's a need
to distrust ec-based ps/2 keyboards that are associated with untrusted
ECs. To help facilitate this, coreboot needs to report more
details about non-usb keyboards, so this change replaces the current
instances of unknown with enum values that distinguish uart and gpio
from ec-based keyboards.
BUG=b:129471321
BRANCH=None
TEST=Local compile and flash to systems with trusted and non-trusted
ECs. Confirmed that security confirmation can't be performed via
keyboard on a system with an untrusted EC but can still be performed
on a system with a trusted EC.
