[U-Boot] [PATCH 06/13] Kconfig: Separate AM33XX SOC config from target board config

[Andrew F. Davis <afd@ti.com>]

The config option AM33XX is used in several boards and should be
defined as a stand-alone option for this SOC. We break this out
from TARGET_AM335X_EVM then enable AM33XX on in all the boards that
used TARGET_AM335X_EVM to eliminate any functional change with
this patch. Also conditionally define this in ti_am335x_common.h to prevent
redefinition. The definition can be removed completely when all platforms
that include this header have this definition added to their defconfig.

This is similar to what has already been done in
9de852642cae ("arm: Kconfig: Add support for AM43xx SoC specific Kconfig")
and is done for the same reasons.
