[PATCH] cpufreq: OMAP: fix build errors: depends on ARCH_OMAP2PLUS

The OMAP driver needs a 'depends on ARCH_OMAP2PLUS' since it only
builds for OMAP2+ platforms.

This 'depends on' was in the original patch from Russell King, but was
erroneously removed by me when making this option user-selectable in
commit b09db45c (cpufreq: OMAP driver depends CPUfreq tables.)  This
patch remedies that.

Apologies to Russell King for breaking his originally working patch.

Also, thanks to Grazvydas Ignotas for reporting the same problem.

Can you please check that you've picked up everything that's necessary,
as I'm still seeing the below as outstanding from my original patch.

    ARM: OMAP: fix cpufreq build
    
    OMAPs cpufreq requires the frequency table support, but nothing ensures
    that this is selected.  This can result in configurations which fail to
    build:
    
    drivers/built-in.o:(.data+0x5238): undefined reference to `cpufreq_freq_attr_scaling_available_freqs'
    drivers/cpufreq/omap-cpufreq.c:88: undefined reference to `cpufreq_frequency_table_target'
    drivers/cpufreq/omap-cpufreq.c:60: undefined reference to `cpufreq_frequency_table_verify'
    drivers/cpufreq/omap-cpufreq.c:186: undefined reference to `cpufreq_frequency_table_cpuinfo'
    drivers/cpufreq/omap-cpufreq.c:190: undefined reference to `cpufreq_frequency_table_get_attr'
    
    Fix this by introducing a new configuration variable and having that
    select CPU_FREQ_TABLE.

Right, I'm fed up with chasing over this trivial patch.  It's been almost
a full month since the problem was first reported and it _still_ remains
unfixed in mainline, despite me chasing over it.  So, sorry, you lose.

I'm merging my fix (attached) which I've been running against the nightly
builds into my fixes branch and will ask Linus to pull it this weekend.
If you want something else, then please send a patch on top of my fix to
do what you want.

Alternatively, send a replacement fix to Linus _before_ Sunday evening
copying me with it and I'll drop this from my tree.  But I want to see
an alternative going to Linus for that to happen.

Subject: [PATCH] ARM: OMAP: fix cpufreq build

OMAPs cpufreq requires the frequency table support, but nothing ensures
that this is selected.  This can result in configurations which fail to
build:

drivers/built-in.o:(.data+0x5238): undefined reference to `cpufreq_freq_attr_scaling_available_freqs'
drivers/cpufreq/omap-cpufreq.c:88: undefined reference to `cpufreq_frequency_table_target'
drivers/cpufreq/omap-cpufreq.c:60: undefined reference to `cpufreq_frequency_table_verify'
drivers/cpufreq/omap-cpufreq.c:186: undefined reference to `cpufreq_frequency_table_cpuinfo'
drivers/cpufreq/omap-cpufreq.c:190: undefined reference to `cpufreq_frequency_table_get_attr'

Fix this by introducing a new configuration variable and having that
select CPU_FREQ_TABLE.
