[PATCH v4 06/12] gpio/omap: fix trigger type to unsigned

The GPIO trigger parameter is of type unsigned.
enum {
        IRQ_TYPE_NONE           = 0x00000000,
        IRQ_TYPE_EDGE_RISING    = 0x00000001,
        IRQ_TYPE_EDGE_FALLING   = 0x00000002,
        IRQ_TYPE_EDGE_BOTH      = (IRQ_TYPE_EDGE_FALLING | IRQ_TYPE_EDGE_RISING),
        IRQ_TYPE_LEVEL_HIGH     = 0x00000004,
        IRQ_TYPE_LEVEL_LOW      = 0x00000008,
        IRQ_TYPE_LEVEL_MASK     = (IRQ_TYPE_LEVEL_LOW | IRQ_TYPE_LEVEL_HIGH),
        IRQ_TYPE_SENSE_MASK     = 0x0000000f,

        IRQ_TYPE_PROBE          = 0x00000010,
...
};
Even though gpio_irq_type(struct irq_data *d, unsigned type) has the right type
of parameter, the subsequent called functions set_gpio_triggering() and
set_gpio_trigger() wrongly makes it signed integer. Fix this.
