clk: samsung: exynos5420: Preserve CPU clocks configuration during suspend/resume
commit e21be0d1d7bd7f78a77613f6bcb6965e72b22fc1 upstream.
Save and restore top PLL related configuration registers for big (APLL)
and LITTLE (KPLL) cores during suspend/resume cycle. So far, CPU clocks
were reset to default values after suspend/resume cycle and performance
after system resume was affected when performance governor has been selected.
