[U-Boot] [PATCH v4 2/2] nitrogen: Use unsigned long to specify the total RAM size

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>>

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

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

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

Changes since v3:
- Use GiB
Changes since v2:
-  move casting inside expression to force using unsigned long (from Stefano) 
Changes since v1:
- No changes
