[U-Boot] [PATCH 1/2] mx6sabresd: Fix SPL memory description

[U-Boot] [PATCH 1/2] mx6sabresd: Fix SPL memory description

[Fabio Estevam]

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

mx6sabresd has four MT41K128M16JT-125 chips. Each memory has 16-bit bus
and 2GiB, so fix the width and density fields accordingly.
