spi: ath79: remove spi-master setup and cleanup assignment

This removes the assignment of setup and cleanup functions for the ath79
target. Assigning the setup-method will lead to 'setup_transfer' not
being assigned in spi_bitbang_init.

Also drop the redundant cleanup assignment, as this also happens in
spi_bitbang_init.
