cpufreq: fix compile-test defaults

Commit 3f66425a ("cpufreq: Enable COMPILE_TEST on Arm drivers")
enabled compile testing of most Arm CPUFreq drivers but left the
existing default values unchanged so that many drivers are enabled by
default whenever COMPILE_TEST is selected.

This specifically results in the S3C64XX CPUFreq driver being enabled
and initialised during boot of non-S3C64XX platforms with the following
error logged:

	cpufreq: Unable to obtain ARMCLK: -2

Commit d4f610a9 ("cpufreq: Do not enable by default during compile
testing") recently fixed most of the default values, but two entries
were missed and two could use a more specific default condition.

Fix the default values for drivers that can be compile tested and that
should be enabled by default when not compile testing.
