[PATCH] gpio: mxc: set the port->irq high to 0 for imx2

[haibo.chen@xxxxxxx]

From: Haibo Chen <haibo.chen@xxxxxxx>

MX2 has one interrupt for all gpio ports, so do not need the value
port->irq_high, need to set to 0. Current setting is -1, which will
meet issue in gpio_set_wake_irq().

Fixes: 5f6d1998adeb ("gpio: mxc: release the parent IRQ in runtime suspend")
