ENGR00232326 MX6x-Fix incorrect I2C bitrate

IPG_PERCLK is the parent of I2C. I2C needs a minimum of
12.8MHz as its input clock to achieve 400KHz speed. Hence
change the IPG_PERCLK speed accordingly.
MX6DQ/MX6DL - Set IPG_PERCLK at 22MHz (sourced from IPG_CLK)
MX6SL - Set IPG_PERCLK to 24MHz(Sourced from 24MHz XTAL).
