There's no need to use threaded IRQs with the PXP, as the interrupt
handler doesn't need to sleep and doesn't perform any time-consuming
operation. Switch to regular IRQ handler.
This fixes lockups of the PXP noticed on i.MX7, where the PXP would stop
generating interrupts after a variable number of frames (from a few
dozens to a few hundreds). The root cause is however unknown.
