Convert the common bridge code and the two rockchip & stm drivers which currently use it to the regmap API in anticipation for further changes to make it more generic and add older DSI host controller support as found on i.mx6 based devices.
The regmap becomes an internal state of the bridge. No functional changes other than requiring the platform drivers to use the pre-configured regmap supplied by the bridge after its probe() call instead of ioremp'ing the registers themselves.
In subsequent commits the bridge will become able to detect the DSI host core version and init the regmap with different register layouts. The platform drivers will continue to use the regmap without modifications or worrying about the specific layout in use (in other words the layout is abstracted away via the regmap).

I should have been clearer earlier - I didn't quite review the patch. Is is now though. Reviewed-by: Emil Velikov <emil.velikov@xxxxxxxxxxxxx>
Admittedly a couple of nitpicks (DRIVER_NAME, zero initialize of val) could have been left out. It's not a big deal, there's no need to polish those.
