Documentation: bindings: move the Berlin pinctrl documentation

The Berlin pinctrl documentation was part of the Marvell Berlin SoC
documentation because the Berlin pinctrl configuration was inside the
chip and the system controllers. With the recent rework of the chip and
system controller handling (now an MFD driver registers all sub-devices
of the two soc and system controller nodes and each device has its own
sub-node), the documentation of the Berlin pinctrl driver can be moved
to the generic pinctrl documentation directory.

-* Pin controller binding
-
-Pin control registers are part of both register sets, chip control and system
-control. The pins controlled are organized in groups, so no actual pin
-information is needed.
-
-A pin-controller node should contain subnodes representing the pin group
-configurations, one per function. Each subnode has the group name and the muxing
-function used.
-
-Be aware the Marvell Berlin datasheets use the keyword 'mode' for what is called
-a 'function' in the pin-controller subsystem.
-
-Required subnode-properties:
-- groups: a list of strings describing the group names.
-- function: a string describing the function used to mux the groups.
