net: microchip: vcap api: Enable/Disable rules via chains in VCAP HW

Browse Source 
This supports that individual rules are enabled and disabled via chain
information.
This is done by keeping disabled rules in the VCAP list (cached) until they
are enabled, and only at this time are the rules written to the VCAP HW.
