ARM: imx: select CPU_FREQ_TABLE when needed
commit f637c4c9405e21f44cf0045eaf77eddd3a79ca5a upstream.
The i.MX cpufreq implementation uses the CPU_FREQ_TABLE helpers,
so it needs to select that code to be built. This problem has
apparently existed since the i.MX cpufreq code was first merged
in v2.6.37.
Building IMX without CPU_FREQ_TABLE results in:
arch/arm/plat-mxc/built-in.o: In function `mxc_cpufreq_exit':
arch/arm/plat-mxc/cpufreq.c:173: undefined reference to `cpufreq_frequency_table_put_attr'
arch/arm/plat-mxc/built-in.o: In function `mxc_set_target':
arch/arm/plat-mxc/cpufreq.c:84: undefined reference to `cpufreq_frequency_table_target'

arch/arm/plat-mxc/cpufreq.c:65: undefined reference to `cpufreq_frequency_table_verify'
arch/arm/plat-mxc/built-in.o: In function `mxc_cpufreq_init':
