[ARM] 4829/1: add .get method to pxa-cpufreq to silence a warning

The .get method is needed for suspend/resume. Otherwise you
get this in dmesg:

cpufreq: suspend failed to assert current frequency is what timing core thinks it is.
cpufreq: resume failed to assert current frequency is what timing core thinks it is.
