[U-Boot] [PATCH 03/13] spl: Kconfig: Add CONFIG_SPL_TEXT_BASE as Kconfig option

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

Add a new Kconfig CONFIG_SPL_TEXT_BASE. Add its use to
am335x_evm_defconfig, then only conditionally define it in
ti_am335x_common.h when it is not already defined, this allows for
systems that have not fully converted to the Kconfig based config
system to still include this header without redefining this symbol
on platforms that have.
