spi: bcm2835: fix device_node reference leak in bcm2835_spi_setup()

of_find_compatible_node() returns a device_node with its reference count
incremented, but bcm2835_spi_setup() only uses the return value to test
for a matching node in the loop and never releases it.

Declare the node with a scope-based __free(device_node) cleanup so the
reference is dropped automatically when leaving the loop body, matching
the existing __free(kfree) usage in the same function.
