mlxsw: spectrum: Assume CONFIG_NET_DEVLINK is always enabled

Since commit f6b19b35 ("net: devlink: select NET_DEVLINK
from drivers") adds implicit select of NET_DEVLINK for
mlxsw, the code does not have to deal with the case
when CONFIG_NET_DEVLINK is not enabled. So remove the ifcase
and adjust Makefile.
