pinctrl: mcp23s08: improve I2C Kconfig dependency
With "SPI_MASTER=y && I2C=m", we can build mcp23s08 as a built-in driver,
which then results in a link failure:
drivers/pinctrl/built-in.o: In function `mcp23s08_probe_one.isra.0':
:(.text+0x7910): undefined reference to `__devm_regmap_init_i2c'
drivers/pinctrl/built-in.o: In function `mcp23s08_init':
:(.init.text+0x110): undefined reference to `i2c_register_driver'
drivers/pinctrl/built-in.o: In function `mcp23s08_exit':
:(.exit.text+0x3c): undefined reference to `i2c_del_driver'
To avoid the problem, this adds another dependency on I2C that enforces
mcp23s08 to be a loadable module whenever the I2C core is a module.
