zero set to rgmii and doesn't count any delay set in a secondary CPU

Currently CPU port is always hardcoded to port 0. This switch have 2 CPU
ports. The original intention of this driver seems to be use the
mac06_exchange bit to swap MAC0 with MAC6 in the strange configuration
where device have connected only the CPU port 6. To skip the
introduction of a new binding, rework the driver to address the
secondary CPU port as primary and drop any reference of hardcoded port.
With configuration of mac06 exchange, just skip the definition of port0
and define the CPU port as a secondary. The driver will autoconfigure
the switch to use that as the primary CPU port.

Currently, NDA_FLAGS_EXT flags allow a maximum of 24 bits to be used for
extended neighbor flags. These are eventually fed into neigh->flags by
shifting with NTF_EXT_SHIFT as per commit 2c611ad9 ("net, neigh:
Extend neigh->flags to 32 bit to allow for extensions").

If really ever needed in future, the full 32 bits from NDA_FLAGS_EXT can
be used, it would only require to move neigh->flags from u32 to u64 inside
the kernel.

Add a build-time assertion such that when extending the NTF_EXT_MASK with
new bits, we'll trigger an error once we surpass the 24th bit. This assumes
that no bit holes in new NTF_EXT_* flags will slip in from UAPI, but I
think this is reasonable to assume.
