[U-Boot] [RFC PATCH 08/11] sunxi: SPL: add FIT config selector for Pine64 boards

[Andre Przywara]

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 to cover the two different Pine64 models,
which can be easily told apart by looking at the amount of installed
RAM.
