add option to de-activate EC console input when WP is on
With a Toad cable, the user can access the EC serial console through the
micro-B connector.
We probably need to de-activate the input on the EC serial console when
the Write-Protect is on, since we have fairly "powerful" commands on the
EC command-line.
Add a new CONFIG_CONSOLE_RESTRICTED_INPUT on platforms with externally
accessible EC serial port.

BRANCH=spring
BUG=chrome-os-partner:18716
TEST=on Spring with CONFIG_CONSOLE_RESTRICTED_INPUT set, try with and without
write-protect, use successfully the EC console in the former case, and see
"Console is DISABLED" in the latter case.
