cpufreq: amd-pstate: optimize the initial frequency values verification
To enhance the debugging capability of the driver loading failure for
broken CPPC ACPI tables, it can optimize the expression by moving the
verification of `min_freq`, `nominal_freq`, and other dependency values
to the `amd_pstate_init_freq()` function where they are initialized.
If any of these values are incorrect, the `amd-pstate` driver will not be registered.
By ensuring that these values are correct before they are used, it will facilitate
the debugging process when encountering driver loading failures due to faulty CPPC
ACPI tables from BIOS
