The DDR3-SDRAM initialization sequence is implemented in
accordance with the DDR3-SRAM/DDR3L-SDRAM initialization section
described in the SAMA5D2 datasheet.
Add registers and definitions of mpddrc controller, which is used
to support DDR3 devices.

Add struct atmel_mpddrc_config to accommodate the mpddrc register
configurations, not using the mpddrc register map structure,
struct atmel_mpddrc, in order to increase readability and reduce
run-time memory use.

The mpddr.c depends on ATMEL_BASE_MPDDRC for the base address to configure the controller.
This cannot be used when there is more than one controller (i.e. AT91SAM9G45, AT91SAM9M10).
