Replace the last instance of acpi_bus_get_device(), added recently
by commit 87e59b36e5e2 ("spi: Support selection of the index of the
ACPI Spi Resource before alloc"), with acpi_fetch_acpi_dev() and
finally drop acpi_bus_get_device() that has no more users.

Or I can take this via the SPI tree?

Thanks!

I'm going to push this for -rc2 so acpi_bus_get_device() is not there
in case somebody has a plan to use it again. :-)
