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.

To enable the clocks on the at91 boards a constant (0x4) is used.
This is replaced with a define in at91_pmc.h (1 << 2).

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).

As the cs for spi is worked in gpio mode, so no need to configure
it as peripheral and then configure to gpio. Configure it to gpio
directly.

This patch configure at91sam9x5's EBI drive I/O. Without this, When SD card boot, the nand flash read/write are not stable. Which will cause kernel MTD test fail (Since mainline kernel doesn't configure the EBI register).

Add at91sam9x5ek board support, this board support the following SoCs
AT91SAM9G15, AT91SAM9G25, AT91SAM9G35, AT91SAM9X25, AT91SAM9X35
Using at91sam9x5ek_nandflash to configure for the board
Now only supports NAND with software ECC boot up
