mlxsw: resources: Add resource identifier for maximum number of FIDs

Add a resource identifier for maximum number of FIDs so that it could be
later used to query the information from firmware.

In Spectrum-2 and Spectrum-3, the correction field of PTP packets which are
sent as control packets is not updated at egress port. To overcome this
limitation, some packets will be sent as data packets. The header should
include FID, which is supposed to be 'Max FID + port - 1'. As preparation,
add the required resource, to be able to query the value from firmware
later.
