Daniel Thompson 8105da265b flash_spi: Generalize to support chips with 24-bit addresses 
Currently flash_spi.py is hardcoded for a small set of devices, all of
which can use 4-byte addressing. Fix this by allowing the command set and
address generation to be switched dynamically.

We also remove the whitelist of tested devices since the interfaces used
is very common amoung different flash devices. However as a safety measure
the user can provide the expected flash size and this will be checked
against the density field.
