cr50: increase receive buffer size
The receive buffer needs to be able to accommodate the largest
commands. Even though the spec sets the size limit at 4096, let's keep

BRANCH=none
BUG=chrome-os-partner:43025
TEST=with the rest of the patches applied, the AES test vectors pass
through without a problem.
