[PATCH] gpio: ge: Fix build warning

[Thierry Reding]

From: Thierry Reding <tred...@nvidia.com>

Casting a pointer to u16 can produce a compiler warning such as this:

    drivers/gpio/gpio-ge.c: In function 'gef_gpio_probe':
    drivers/gpio/gpio-ge.c:83:14: warning: cast from pointer to integer of 
different size [-Wpointer-to-int-cast]
        gc->ngpio = (u16)of_device_get_match_data(&pdev->dev);
                    ^

Cast the pointer through a uintptr_t to avoid the warning.
