MIPS: Fix build for LTS kernel caused by backporting lpj adjustment
Commit ed26aacfb5f71eecb20a ("mips: Add udelay lpj numbers adjustment")
has backported to 4.4~5.4, but the "struct cpufreq_freqs" (and also the
cpufreq notifier machanism) of 4.4~4.19 are different from the upstream
kernel. These differences cause build errors, and this patch can fix the
build.
