Subject: [PATCH net-next] cnic: Fix Kconfig warning without MMU

If MMU is not set, Kconfig warning this:

WARNING: unmet direct dependencies detected for UIO
  Depends on [n]: MMU [=n]
  Selected by [y]:
  - CNIC [=y] && NETDEVICES [=y] && ETHERNET [=y] && NET_VENDOR_BROADCOM [=y] && PCI [=y] && (IPV6 [=y] || IPV6 [=y]=n)

Make CNIC depend on UIO instead of select it to fix this.
