Lukas Wunner 9d16996369 spi: bcm2835: Fix use-after-free on unbind
commit e1483ac030 upstream

bcm2835_spi_remove() accesses the driver's private data after calling
spi_unregister_controller() even though that function releases the last
reference on the spi_controller and thereby frees the private data.

Fix by switching over to the new devm_spi_alloc_master() helper which
keeps the private data accessible until the driver has unbound.
