imx: mx6sxsabreauto: enable more dm drivers

Enable MMC/I2C/GPIO/PMIC/REGULATOR/PCA953X DM drivers
for mx6sxsabreauto board. Drop non-DM code.

Note:
The i.MX DM drivers has such dependency.
  MXC GPIO -> MXC I2C -> PFUZE/REGULATOR
  MXC GPIO -> PCA953X
  MXC GPIO -> FSL_USDHC

So the drivers needs to be enabled all to avoid
compiling error.
