CPUFREQ of S5PV210 uses different APLL settings and we provide
such values for CPUFREQ at pll.h. We have been using differently
between EVT0 and EVT1 machines. Although this version of kernel
assumes that the CPU is EVT1, users may use code for EVT0 later.
Note that at 1GHz of ARMCLK, APLL should be 1GHz and for other lower
ARMCLK, APLL should be 800MHz.
