spi: Remove explictly set bus_num and num_chipselect to default setting

The purpose of commit 1e8a52e "spi: By default setup spi_masters with 1 chipselect and dynamics bus number" is to avoid setting default value for bus_num and num_chipselect in spi master drivers. So let's remove the duplicate code.
