am335x: Clean up/fix some settings in the am335x Kconfig. 

Some settings in the am335x Kconfig weren't actually used for anything, some
where place holders, and some where left over from another CPU. The memory
addresses are in the internal RAM in the SOC as described in the reference
manual. The stack is put where the internal ROM had its stack, and the
bootblock is put at the bottom of that region as the manual suggests. The
ROM stage offset is set to 10K which is a bit bigger than the ~7.5K the
bootblock currently takes up.
