spi: Remove explictly set bus_num and num_chipselect to default setting 



The purpose of commit 1e8a52e1
"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.
