Add documentation to describe the "Other Logic Block" system-controller.
It deals with three platforms: EyeQ5, EyeQ6L and EyeQ6H. First two have
a single instance, whereas EyeQ6H has seven named instances.

Features provided are:
 - Clocks, children to main crystal. Some PLLs and divider clocks.
 - Resets. Some instances DO NOT have reset.
 - Pinctrl. Only EyeQ5 has such feature.

Those are NOT the only features exposed in OLB system-controllers! Many
individual registers, related to IP block integration, can be found.
Additional features will be exposed over time.

We simplify devicetree phandles to OLB in two ways:

 - Compatibles exposing a single clock do not ask for a index argument.
   This means we use EyeQ6H OLB south (it has four clocks):

      clocks = <&olb_south EQ6HC_SOUTH_PLL_PER>;

   But use EyeQ6H OLB east (it has one clock):

      clocks = <&olb_east>;

 - Compatibles exposing a single reset domain do not ask for a domain
   index, only a reset index.
   This means we use EyeQ5 OLB (it has three domains):

     resets = <&olb 0 10>;

   But use EyeQ6H west reset (it has one domain):

      resets = <&olb_west 3>;

About pinctrl subnodes: all pins have two functionality, either GPIO or
something-else. The latter is pin dependent, we express constraints
using many if-then.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
