The gpmi's IP for imx6sx is nearly the same as the gpmi's IP for imx6q,
except the following two new features:
(1) the new BCH contoller has 62-BIT correcting ECC strength
(The BCH for imx6q only has 40-BIT ECC strength).
(2) add the hardware Randomizer support.
This patch does the follow changes:
(1) add a new macro GPMI_IS_MX6SX to represent the imx6sx's gpmi.
(2) add a new macro GPMI_IS_MX6.
We use this macro to initialize the same registers for both
imx6sx and imx6q, and so on.
(3) add a new gpmi_devdata instance, the gpmi_devdata_imx6sx, for
imx6sx.
