The capabilities bitfield was converted to a 64-bit value, but a cap_bit
in struct mtk_eth_muxc which is used to store a full bitfield (rather
than the bit number, as the name would suggest) still holds only a
32-bit value.

Change the type of cap_bit to u64 in order to avoid truncating the
bitfield which results in path selection to not work with capabilities
above the 32-bit limit.
