ENGR00313202 ARM: imx: add VPU 352M support for i.MX6Q
When VPU freq is set to 352MHz, it need to source clk
from PLL2_PFD2_396M, and PLL2_PFD2_396M need to change
freq to 352M.
VDDSOC/PU needs to be at highest setpoint when VPU@352Mhz,
cpufreq will be disabled as it will not save any power if
VDDSOC/PU's voltage stays at highest setpoint.
Busfreq will be disabled as it needs PLL2_PFD2 to be
as 396MHz to achieve low power audio freq setpoint.
To enable VPU 352MHz feature, select it in menuconfig,
it is disabled by default.
