raiden_debug_spi: Use spi data in configure_protocol

Spi data for this programmer now contains pointer to spi_master
struct, and can be used in configure_protocol.

This patch is making init code of raiden_debug_spi a bit more
consistent with other programmers, for example it allows to remove
data assignment `spi_config->data = data` from init function. This
assignment was only needed for configure_protocol function, and
now it is not needed anymore.
