[U-Boot] [PATCH-OMAP3 v2] OMAP3: Fix error in gpmc_init

[dirk.behme at googlemail.com]

Fix error in gpmc_init() introduced with readl/writel conversion. Use base
addresses + offset, not offset only. Minor clean up by removing unused code.

Changes in v2:

- Correct patch header style.

v2 of this patch makes previous version v1 obsolete.

Jean-Christophe: Would be nice if you could handle this patch with priority 
as it prevents BeagleBoard from starting. Thanks!
