#1616109 — [PATCH v4 7/8] mfd: tps6105x: Add OF device ID table

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have a
OF device ID table if the devices are registered via OF.

Changes in v4: None
Changes in v3:
- Add a vendor prefix to the compatible string (Rob Herring).

Changes in v2:
- Don't use of_match_ptr() to avoid build warning when CONFIG_OF is disabled.
