Let the programmer driver decide how to do AAI transfers

Currently spi_aai_write() is implemented without an abstraction
mechanism for the programmer driver. This adds another function
pointer 'write_aai' to struct spi_programmer, which is set to
default_spi_write_aai (renamed spi_aai_write) for all programmers
for now.

A patch which utilises this abstraction in the dediprog driver will
follow.
