Subject: [Patch net] net: dsa: microchip: remove IRQF_TRIGGER_FALLING in request_threaded_irq

KSZ swithes used interrupts for detecting the phy link up and down.
During registering the interrupt handler, it used IRQF_TRIGGER_FALLING
flag. But this flag has to be retrieved from device tree instead of hard
coding in the driver, so removing the flag.

Fixes: ff319a644829 ("net: dsa: microchip: move interrupt handling logic from lan937x to ksz_common")
