This driver will get support for more SoCs and the list of infracfg
compatibles is expected to grow: in order to prevent getting this
situation out of control and see a long list of compatible strings,
add support to retrieve a handle to infracfg's regmap through a
new "mediatek,infracfg" phandle.
In order to keep retrocompatibility with older devicetrees, the old
way is kept in place.
