Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.

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.

Instead of passing the total RAM size via PHYS_SDRAM_SIZE option,
we should better use imx_ddr_size() function, which automatically
determines the RAM size.

Most of ehci-fsl header describe USB controller
designed by Chipidea and used by various SoC vendors.

This patch renames it to a generic header: ehci-ci.h
Contents of file are not changed (so it contains several
references to freescale SoCs).
