iio: magn: mmc5633: Fix Kconfig for combination of I3C as module and driver builtin

Fix based on similar fix in:
commit 83b645e ("hwmon: tmp108: fix I3C dependency")

Note to keep things simple I'm now requiring I2C.
That can probably be relaxed in future, but I want to reduce the test
set of builds for now given this is blocker for the main IIO pull request.

Fixes: e559c86 ("iio: magn: mmc5633: Ensure REGMAP_I2C / I3C not build if I2C / I3C is not.")
