mx6: Add board mx6memcal for use in validating DDR
This is a virtual "board" that uses configuration files and
Kconfig to define the memory layout used by a real board during
the board bring-up process.
It generates an SPL image that can be loaded using imx_usb or
SB_LOADER.exe.
When run, it will generate a set of calibration constants for
use in either or both a DCD configuration file for boards that
use u-boot.imx or struct mx6_mmdc_calibration for boards that
boot via SPL.
In essence, it is a configurable, open-source variant of the
Freescale ddr-stress tool.

File mx6memcal_defconfig configures the board for use with
mx6sabresd or mx6qsabreauto.
