[U-Boot] Update at91sam9m10g45 SoC and AT91SAM9M10G45-EK board to new style

[Thomas Petazzoni]

Hello,

These two patches update the support of the AT91SAM9M10G45 SoC and the
corresponding AT91SAM9M10G45-EK evaluation platform to the next AT91
organization.

For the moment, only the nandflash configuration is supported, the
dataflash configuration will come later on.

Note however that the AT91 Ethernet driver doesn't work in the current
master, due to the D-cache being enabled by
c2dd0d45540397704de9b13287417d21049d34c6. Waiting for a proper
solution to this problem, I am currently doing the testing with the
following workaround:

diff --git a/arch/arm/lib/board.c b/arch/arm/lib/board.c
index 90709d0..761e233 100644
--- a/arch/arm/lib/board.c

+#if 0
        dcache_enable();

        debug ("monitor flash len: %08lX\n", monitor_flash_len);
        board_init();   /* Setup chipselects */
