There is no way to build U8500 kernels without an MMU
at this point because of dependencies on MMU-only functions.
As long as nobody is interested in fixing this, let's just disable
the platforms for nommu kernels.

At least one platform needs to be selected, so pick the u8500
development board if nothing else is selected. The first
menu to choose the actual platform is meaningless and can be
made invisible.

The ux500 platform requires CPU_FREQ_TABLE support to be enabled for its
CPU_FREQ implementations, so automatically select that when CPU_FREQ

This one has actually become obsolete now, the MFD_SUPPORT
option was recently removed.
