i2c: mux: pca954x: fix dependencies
This driver causes the following randconfig build error:
drivers/i2c/muxes/i2c-mux-pca954x.c: In function ‘pca954x_probe’:
drivers/i2c/muxes/i2c-mux-pca954x.c:204:2: error: implicit declaration
of function ‘devm_gpiod_get’ [-Werror=implicit-function-declaration]
gpio = devm_gpiod_get(&client->dev, "reset");
^
drivers/i2c/muxes/i2c-mux-pca954x.c:204:7: warning: assignment makes
pointer from integer without a cast [enabled by default]
gpio = devm_gpiod_get(&client->dev, "reset");

cc1: some warnings being treated as errors
make[3]: *** [drivers/i2c/muxes/i2c-mux-pca954x.o] Error 1
This is because it is getting compiled without gpiolib, so
introduce an explicit dependency.
