gpio: msm-common: Fix irq_set_type for dual edge trigger 

msm_gpio_update_dual_edge_pos() function will set correct
trigger type based on the current gpio level in case that
the interrupt type is both edge trigger type (IRQF_TRIGGER_RISING
|IRQF_TRIGGER_FALLING). Later again we set the msm_gpio_irq_extn
set_type with mpm to set it as IRQF_TRIGGER_RISING.

Avoid configuring the type with mpm if it is dual edge trigger.
