greybus: greybus-driver: Add intf_oops operation

Add intf_oops operation to SVC Protocol. This
operation will notify the AP about a fatal error
in a module. The request has two arguments:
    -u8 intf - the interface in question
    -u8 reason - reason of the error
The response has no payload.
Upon receiving the Request, the driver disables
the Interface.
