cpufreq: preserve freq_table_sorted across suspend/hibernate
During S3/S4 suspend and resume, cpufreq policies are not freed or
recreated; the freq_table and policy structure remain intact. However,
set_freq_table_sorted() currently resets policy->freq_table_sorted to
UNSORTED unconditionally, which is unnecessary since the table order
does not change across suspend/resume.
This patch adds a check to skip validation if policy->freq_table_sorted
is already ASCENDING or DESCENDING. This avoids unnecessary traversal
of the frequency table on S3/S4 resume or repeated online events,
reducing overhead while preserving correctness.
