gpio: raspberrypi-ext: fix firmware dependency
When the firmware driver is a loadable module, the gpio driver cannot be
built-in:
drivers/gpio/gpio-raspberrypi-exp.o: In function `rpi_exp_gpio_set':
gpio-raspberrypi-exp.c:(.text+0xb4): undefined reference to `rpi_firmware_property'
drivers/gpio/gpio-raspberrypi-exp.o: In function `rpi_exp_gpio_get':
gpio-raspberrypi-exp.c:(.text+0x1ec): undefined reference to `rpi_firmware_property'
drivers/gpio/gpio-raspberrypi-exp.o: In function `rpi_exp_gpio_get_direction':
gpio-raspberrypi-exp.c:(.text+0x360): undefined reference to `rpi_firmware_property'
drivers/gpio/gpio-raspberrypi-exp.o: In function `rpi_exp_gpio_get_polarity':
gpio-raspberrypi-exp.c:(.text+0x4d4): undefined reference to `rpi_firmware_property'
drivers/gpio/gpio-raspberrypi-exp.o: In function `rpi_exp_gpio_dir_out':
gpio-raspberrypi-exp.c:(.text+0x670): undefined reference to `rpi_firmware_property'
drivers/gpio/gpio-raspberrypi-exp.o:gpio-raspberrypi-exp.c:(.text+0x7fc): more undefined references to `rpi_firmware_property' follow
drivers/gpio/gpio-raspberrypi-exp.o: In function `rpi_exp_gpio_dir_in':
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.
