allwinner: Move SEPARATE_NOBITS_REGION to platforms 

For the existing SoCs we support, we use SEPARATE_NOBITS_REGION, to move
some parts of the data into separate memory regions (to save on the SRAM
A2 we are loaded into).
For the upcoming H616 platform this is of no concern (we run in DRAM),
so make this flag a platform choice instead.
