cpufreq_frequency_table_verify() is a bit rewritten here to make it more logical and optimal. - merge multiple lines for variable declarations together. - quit early if any frequency between min/max is found. - don't call cpufreq_verify_within_limits() in case any valid freq is found as it is of no use. - count renamed as found and made a boolean.
