4245701ef5 arm: at91/spl: mpddrc: use IP version to check configuration
To remove the unnecessary #ifdef-endif, use the mpddrc IP version
to check whether or not the interleaved decoding type is supported.

c2ad76c4bd arm: at91/spl: mpddrc: add mpddrc DDR3-SDRAM initialization
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.

7e8702a00f arm: at91/spl: mpddrc: add struct atmel_mpddrc_config
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.

0c01c3e876 arm: at91: mpddr: allow multiple DDR controllers
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).
