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.

At present CONFIG_CMD_SATA enables the 'sata' command which also brings
in SATA support. Some boards may wish to enable SATA without the command.
Add a separate CONFIG to permit this.

There is no dedicated reset signal wired up for the MX6QDL thus if the
bootloader enables the link we need some special handling to get the core
back into a state where it is safe to touch it for configuration.
While there has been some special handling in the Linux kernel to do this,
it was removed in 4.11 thus we need to do it properly in the bootloader
and therefore without this if you enable PCI in the bootloader you will hang
while booting the 4.11 kernel.
This puts the PCIe controller back into a safe state for the kernel driver
before launching the kernel.

Ideally, the Linux kernel should get the hardware in its most
untouched state. For the most part, U-Boot does not reset the various
subsystems it touches before boot, and usually Linux deals with it, but
on some boards (cm_fx6) the Linux kernel fails to detect the ssd
correctly if sata is used by U-Boot.
Power off sata on OS boot so that Linux will have a clean state to work
with.

The MX6 DRAM controller can be configured to handle 4GiB of DRAM, but
only 3840 MiB of that can be really used. In case the controller is
configured to operate a 4GiB module, the imx_ddr_size() function will
correctly compute that there is 4GiB of DRAM in the system. Firstly,
the return value is 32-bit, so the function will effectively return
zero. Secondly, the MX6 cannot address the full 4GiB, but only 3840MiB
of all that. Thus, clamp the returned size to 3840MiB in such case.

i.MX can profit of the same shared code. Move these files
