spi: rockchip: Use plain request_irq()

The Rockchip driver has since interrupt support was added used
request_threaded_irq() but not actually supplied a threaded handler,
handling everything in the primary handler.  This is equivalent to just
using a plain request_irq(), and since aef30c8 (genirq: Warn about
using IRQF_ONESHOT without a threaded handler) the current behaviour has
triggered a WARN_ON().  Convert to use request_irq().
