pinctrl: qcom: Update irq handle for GPIO pins

Default handle_irq for tlmm irq chip is handle_edge_irq. For direct
connect GPIOs, the handle_irq is not changed unlike non-direct connect
GPIOs. This causes an interrupt storm for level trigger types as
handle_edge_irq does not mask the interrupt within the function. Change
this to handle_fasteoi_irq such that both level and edge interrupts are
handled correctly.
