hwmon: Remove redundant spi driver bus initialization

Author: Lars-Peter Clausen <lars@metafoo.de>

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_register_driver(),
so we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:
// 
@@
identifier _driver;
@@
struct spi_driver _driver = {
	.driver = {
-		.bus = &spi_bus_type,
	},
};
//
