lib/Kconfig: Remove RAMSTAGE_CBMEM_TOP_ARG 

All targets now have the _cbmem_top_ptr symbol populated via calling
arguments or in the nvidia/tegra210 case worked around by populating
it with cbmem_top_chipset explicitly at the start of ramstage, so the
Kconfig guarding this behavior can be removed.
