hammer: Support different IC types in touchpad FW update
Some Elan touchpad ICs have a different firmware sizes (48, 56, or 64
KB). We use CONFIG_TOUCHPAD_VIRTUAL_SIZE, set in the board file, to
determine the appropriate size, and, at runtime, we sanity check the
firmware size according to the IC type reported by the touchpad.
BRANCH=none
BUG=b:65188846
TEST=Manually modify the CONFIG_TOUCHPAD_VIRTUAL_SIZE in hammer,
executed and verified both (1) "EC_ERROR_UNKNOWN" returned
(2) ic_type shows 0x09 on EC console
TEST=Successfully flashing 48k firmware using CL:658920 on hammer and
56k firmware on staff. With success here, we specifically test
with different firmware version and make sure it reflected in
hammerd's touchpad info.
