[PATCH] ARM: imx_v6_v7_defconfig: Enable cpufreq governors

Enable more common cpufreq governors in imx defconfig because this is
very useful for testing. In particular you can't use cpufreq-set -f
$FREQ without explicitly defining CONFIG_CPU_FREQ_GOV_USERSPACE=y.

It might make sense for all governors to be enabled by default from
drivers/cpufreq/Kconfig and allow defconfigs to be shorter.
Right now the descriptions for some of them includes a line that says
"If in doubt, say Y" but the config options don't have actually have a
default value defined and they effectively default to N.

Cycling via savedefconfig on shawnguo/for-next also generates some
reordering for some newly added options CONFIG_TOUCHSCREEN_MAX11801=y
and CONFIG_HID_MULTITOUCH=y. Those were not included but it's strange
that this happens. Maybe those options were inserted manually, or
otherwise there is an annoying bug in kconfig?
