ENGR00326994 iMX6: Checking PLL2 PFD0 and PFD2 for periph_clk before reset
u-boot v2014 upstream codes have a problem in pfd reset (s_init function)
that imx6 Dual is not applied for PLL2 PFD2 reset. It is originated by
using dynamical cpu type checking and introducing two cpu types:
MXC_CPU_MX6Q and MXC_CPU_MX6D for iMX6 Dual/Quad platform.
Fixed this problem by checking the pre_periph_clk_sel and pre_periph2_clk
of CCM CBCMR register, if the PLL2 PFD0 or PLL2 PFD2 is used for the clock
source, do not reset this PFD to avoid system hang.
