spi: By default setup spi_masters with 1 chipselect and dynamics bus number
Trivial simplification. Instead of requiring spi master drivers to always set the bus number (even when a dynamic number is desired), this patch modifies spi_alloc_master() to initialize num_chipselect to 1 (because there will always be at least one CS) and bus_num to -1 for dynamic allocation. This simplifies the code needed to be written for drivers. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
