net: hns3: PF support get multicast MAC address space assigned by firmware
The new firmware supports to divides the whole multicast MAC address space
equally to functions of all PFs, and calculates the space size of each PF
according to its function number.
To support this feature, PF driver adds querying multicast MAC address
space size from firmware and limits used number according to space size.
