drm: bridge: dw_mipi_dsi: add initial regmap infrastructure


In order to support multiple versions of the Synopsis MIPI DSI host
controller, which have different register layouts but almost identical
HW protocols, we add a regmap infrastructure which can abstract away
register accesses for platform drivers using the bridge.

The controller HW revision is detected during bridge probe which will
be used in future commits to load the relevant register layout which
the bridge will use transparently to the platform drivers.
