cxl: Deny Features commands on the RAW mailbox path
The RAW mailbox command path allows user to issue arbitrary opcodes
to the device. The FWCTL interface was introduced to support the
CXL Features commands where access control is provided depends on
what the CEL indicates.
Add the Features commands to cxl_disabled_raw_commands[] to ensure
that all Features commands are only accessible through the FWCTL
interface.
The cxl_raw_allow_all debugfs override knob bypasses the disabled list
if the user is aware of the risks and wants to use the RAW path for
Features commands.
