arm64: Set 16 byte alignment and ramstage start address
To align with arm use the RAMSTAGE_BASE Kconfig option
for start of ramstage. Also, use 16-byte alignment for the
start and end of the sections. 4 bytes were previously used, but
it definitely seems more appropriate to at least have the heap
handing out 16-byte aligned pointers.
