[U-Boot] [PATCH] fdt_support: Use CONFIG_NR_DRAM_BANKS if necessary

[Lukasz Majewski <lukma@denx.de>]

Hi Ramon,

> If CONFIG_NR_DRAM_BANKS is bigger than the default
> value (4) define MEMORY_BANKS_MAX as CONFIG_NR_DRAM_BANKS.

Also the Odroid XU3 uses 8 banks (but this is the fault of the board as
it has 4x512MiB probably).

I would also prefer to have the CONFIG_NR_DRAM_BANKS set to 4 (as it
was) and provide patch to convert it to Kconfig.
