arm64: mvebu: pinctrl: Add pin control driver for A8K family
Add a DM port of Marvell pin control driver.
The A8K SoC family contains several silicone dies interconnected
in a single package. Every die is normally equipped with its own
pin controller unit.
There are 2 pin controllers in A70x0 SoC and 3 in A80x0 SoC.
