raiden_debug_spi: Link spi_master struct to spi data

Browse Source 
For this programmer, spi_master struct is dynamically allocated
and needs to be freed on shutdown. Adding a pointer to spi data
struct allows to link spi_master from spi data, which in turn allows
to pass spi data into shutdown function. As a result, both
register_spi_master and register_shutdown use the same data, and
this unblocks moving raiden_debug_spi to new API (like all the
other spi masters in commit a69c5196d20d136b1de120f0fa5ea1e06c3776da).
