Several registers referenced in this driver's source code do not
actually exist (they are not writable and read as zero in my testing).
They exist in this driver because it originated as a copy of the dm9601
driver. Notably, these include the multicast filter registers - this
causes the driver to not support multicast packets correctly. Remove
the multicast filter code and register definitions. Instead, set the
chip to receive all multicast filter packets when any multicast
addresses are in the list.

This device does not have a MII, even though the driver
contains code to drive one (because it originated as a copy of the
dm9601 driver). It also only supports 10Mbps half-duplex
operation (the DM9601 registers to set the speed/duplex mode
are read-only). Remove all MII-related code and implement
sr9700_get_link_ksettings which returns hardcoded correct
information for the link speed and duplex mode. Also add
announcement of the link status like many other Ethernet
drivers have.

The commone register macors (e.g. RSR) is too commont to drivers, it may
be conflict with the architectures (e.g. xtensa, sh).
The related warnings (with allmodconfig under xtensa):
