When the firmware driver is a loadable module, the gpio driver cannot be
built-in:

gpio-raspberrypi-exp.c:(.text+0xb4): undefined reference to
`rpi_firmware_property'

drivers/gpio/gpio-raspberrypi-exp.o: In function `rpi_exp_gpio_probe':
gpio-raspberrypi-exp.c:(.text+0x93c): undefined reference to `rpi_firmware_get'
We already have a Kconfig dependency for it, but when compile-testing, it
is disregarded.
This changes the dependency so that compile-testing is only done when the
firmware driver is completely disabled.

Turn on GPIO support for the expander on Raspberry Pi 3 boards, using
the firmware mailbox to communicate with VideoCore on BCM283x chips.
