refactor(allwinner): move DTB change code into allwinner/common
So far the H616 was the only Allwinner SoC needed to amend the DTB, to
reserve the DRAM portion that BL31 occupies.
To allow other SoCs to modify the DTB as well, without duplicating code,
move the DTB change routines into Allwinner common code, and generalise
the current code to allow other modifications.
No functional change intended.
