am335x: Add the config variable ROMSTAGE_BASE to the CPU's Kconfig.

This variable wasn't being defined and was defaulting to zero when used in the
    ROM stage's linker script. This change defines it as a variable, and gives it
    a value which is slightly beyond the end of the bootblock. By making the ROM
    stage request to be loaded slightly farther into memory than it was loaded by
    the SOC's masked ROM, we ensure that it's moved away from the stage's metadata
    instead of on top of it. When it moves the other way, it clobbers important
    values like the entry point vefore the bootblock has had a chance to use them.
