net: broadcom CNIC: requires MMU

[ Upstream commit 14483cbf040fcb38113497161088a1ce8ce5d713 ]

The CNIC kconfig symbol selects UIO and UIO depends on MMU.
Since 'select' does not follow dependency chains, add the same MMU
dependency to CNIC.

Quietens this kconfig warning:

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