Restrict ME bridging commands

Restrict sensitive ME commands sent via BMC bridging
commands, and return invalid field in request as response
for those.

Tested:
Verified response invalid field in request for the following
ipmitool -t 0x2C -b 0x1 raw 0x6 0x52 0x57 0x0 0x20 0x1 0x0
and got proper response for
ipmitool -t 0x2C -b 0x1 raw 6 1
