MIPS: Alchemy: Fix cpu clock calculation The current code uses bits 0-6 of the sys_cpupll register to calculate core clock speed. However this is only valid on Au1300, on all earlier models the hardware only uses bits 0-5 to generate core clock. This fixes clock calculation on the MTX1 (Au1500), where bit 6 of cpupll is set as well, which ultimately lead the code to calculate a bogus cpu core clock and also uart base clock down the line.
