spi: spi-fsl-lpspi: Use IRQF_NO_AUTOEN flag in request_irq()

Browse source

[ Upstream commit 003c7e0191 ]

disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable when request IRQ.

Fixes: 9728fb3ce1 ("spi: lpspi: disable lpspi module irq in DMA mode")
