mxm_wifiex: fix oob irq request fail on i.MX93 9x9 qsb board

Browse source 
i.MX93 9x9 qsb board connect the out-of-band WoWLAN irq pin(M.2 pin21
SDIO_WAKE) to I2C IO expander pcal6524 instead of i.MX GPIO, pcal6524
IRQ handlers need to be threaded, and the IRQ trigger type depends on
the devicetree setting. Also the IRQF_ONESHOT flag need to be set for
threaded IRQ.
