Subject[PATCH] mfd: wm8350-i2c: make sure the i2c regmap functions are compiled
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

Fixes: 52b461b86a9f ("mfd: Add regmap cache support for wm8350")
