[U-Boot] [PATCH V4] nitrogen: Use unsigned long to specify the total RAM size

[Stefano Babic]

From: "fabio.estevam at freescale.com" <fabio.estevam at freescale.com>

When building for the nitrogen boards with 2GB the following warning happens:

nitrogen6x.c:89:38: warning: integer overflow in expression [-Woverflow]

2GB can not fit in 32-bits, so use ulong instead.

Changes since V2:
	- move casting inside expression to force using unsigned long
