ENGR00221102-1 MX6Q: increase VPU frequence to 352Mhz
Increase VPU frequency to 352Mhz for TV box, use pll2_pfd_400M.To avoid impact
other code which assume ARM clock sourcing from pll2_pfd_400M, change cpu
setpoint of 396M to 352M. and disable bus freq adjust.
add CONFIG_MX6_VPU_352M to choose it, default is disabled.
