cpufreq: powernow-k8: Re-order the init checks

Browse Source 
The powernow-k8 driver will do checks at startup that the current
active driver is acpi-cpufreq and show a warning when they're not
expected.

Because of this the following warning comes up on systems that
support amd-pstate and compiled in both drivers:
`WTF driver: amd-pstate`

The systems that support powernow-k8 will not support amd-pstate,
so re-order the checks to validate the CPU model number first to
avoid this warning being displayed on modern SOCs.
