[U-Boot] [PATCH] include: configs: Fix build warnings due to redefined

[suniel.spartan at gmail.com]

From: Suniel Mahesh <suniel.spartan at gmail.com>

Driver model for OMAP24XX and later Multichannel SPI master controller,
if used, OMAP3 SPI configuration is set.
The same configuration is defined in ti_armv7_omap.h, because
of redefinition, warnings are spilled during build.

Fixed warnings for AM335x SOC by using #ifndef directive in
ti_armv7_omap.h.

Note:
Tested on Beaglebone Black using latest u-boot mainline tree
with device tree set
