[PATCH 6/6] ARM: OMAP: fix cpufreq build

[Russell King]

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.
