Without gpiolib, this driver fails to link:

arm-linux-gnueabi-ld: drivers/hid/hid-mcp2221.o: in function `mcp2221_probe':
hid-mcp2221.c:(.text+0x1b0): undefined reference to `devm_gpiochip_add_data'
arm-linux-gnueabi-ld: drivers/hid/hid-mcp2221.o: in function `mcp_gpio_get':
hid-mcp2221.c:(.text+0x30c): undefined reference to `gpiochip_get_data'

Thanks Arnd, How about one liner:
depends on USB_HID && I2C && GPIOLIB

These days we can even do select GPIOLIB, but I suppose
that would make the driver selectable on platforms with no
native GPIO support at all (like UM) so I suppose this
is better.
