ice: Allow ignoring opcodes on specific VF
Declare bitmap of allowed commands on VF. Initialize default
opcodes list that should be always supported. Declare array of
supported opcodes for each caps used in virtchnl code.
Change allowed bitmap by setting or clearing corresponding
bit to allowlist (bit set) or denylist (bit clear).
