sunxi: SPL: add FIT config selector for Pine64 boards

Browse Source 
For a board or platform to support FIT loading in the SPL, it has to
provide a board_fit_config_name_match() routine, which helps to select
one of possibly multiple DTBs contained in a FIT image.
Provide a simple function which chooses the DT name U-Boot was
configured with.
If the DT name is one of the two Pine64 versions, determine the exact
model by checking the DRAM size.
