armv7/exynos5250/snow: deprecate CONFIG_{RAMBASE,RAMTOP}

Browse Source 
RAMBASE and RAMTOP are leftovers from the x86 port and do not apply
the same way on ARM platforms. On x86 they refer to the low memory
region where coreboot tables reside.

However on ARM we don't have such a region which is architecturally
defined. So instead we'll use the CPU-defined DRAM base address and
the mainboard-defined DRAM size.

This also has the pleasant side-effect of fixing the coreboot tables
to not clobber ramstage code...
