A system configured without CONFIG_CPUFREQ will return 0 for cpufreq_get().
greybus-timesync can subsequently then do a divide-by-zero as result. This
patch fixes by checking for a zero return value from cpufreq_get() and
setting to a default value of 19.2MHz.

Currently, if info is null, the dev_err message is dereferencing an
uninitialized module pointer. Instead, it should use codec->dev pointer
in dev_err call and better align with other err msg in this function.
Also, ret variable might be used uninitialized in a specific case.
Avoid using it this way.
