Kevin Chen e3d1bbdb08 feat(ast2700): set up CPU clock frequency by SCU 
Modify generic timer frequency by SCU setting
1. check SCU_CPU_HW_STRAP1 using HPLL or MPLL
  SCU_CPU_HW_STRAP1[4]=1, using HPLL
  SCU_CPU_HW_STRAP1[4]=0, using MPLL

2. read HPLL or MPLL
  HPLL: frequency setting in SCU_CPU_HW_STRAP1[2:3]
  MPLL: CLKIN_25M with mul and div setting from SCU_CPU_MPLL
