Sebastian Hesselbarth 1217b790ae pinctrl: mvebu: move resource allocation to SoC specific drivers 
The way that mvebu pinctrl is designed, requesting mpp registers
in common pinctrl driver does not allow SoC specific drivers to
access this resource.

Move resource allocation in each SoC pinctrl driver and enable
already provided mpp_{set,get} callbacks.

* This file supports the three variants of Armada XP SoCs that are
* available: mv78230, mv78260 and mv78460. From a pin muxing
* perspective, the mv78230 has 49 MPP pins. The mv78260 and mv78460
* both have 67 MPP pins (more GPIOs and address lines for the memory
* bus mainly). The only difference between the mv78260 and the
* mv78460 in terms of pin muxing is the addition of two functions on
* pins 43 and 56 to access the VDD of the CPU2 and 3 (mv78260 has two
* cores, mv78460 has four cores).
