pinctrl: berlin: prepare to use regmap provided by syscon 

The Berlin pin controller nodes will be simple-mfd probed sub-nodes of
soc-controller and system-controller nodes. The register bank is managed
by syscon, which provides a regmap.

Prepare to get the regmap from syscon parent node instead of SoC stub
provided regmap.
