mfd: wm8350-i2c: Make sure the i2c regmap functions are compiled

commit 88003fb10f1fc606e1704611c62ceae95fd1d7da upstream.

This fixes a compile failure:

	drivers/built-in.o: In function `wm8350_i2c_probe':
	core.c:(.text+0x828b0): undefined reference to `__devm_regmap_init_i2c'
	Makefile:953: recipe for target 'vmlinux' failed
