dt-bindings: gpu: arm,mali: restrict opp-table to objects

Simple 'opp-table:true' accepts a boolean property as opp-table, so
restrict it to object to properly enforce real OPP table nodes.

dt-bindings: gpu: mali-utgard: Add the #cooling-cells property

The GPU can be one of the big heat sources on a SoC. Allow the
"#cooling-cells" property to be specified for ARM Mali Utgard GPUs so
the GPU clock speeds (and voltages) can be reduced to prevent a SoC from
overheating.

dt-bindings: Add missing 'additionalProperties: false'

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

dt-bindings: Clean-up regulator '-supply' schemas

Regulator '*-supply' properties are always a single phandle, so
'maxItems: 1' or a $ref is not necessary. All that's needed is either
'true' or an optional 'description'. Following this clean-up, the
meta-schema will enforce this pattern.

There's one case in tree with 'innolux,n156bge-l21' having 2 phandles.
This appears to be a mistake or abuse of simple-panel as it's 2 different
voltage rails connected to 'power-supply'.

dt-bindings: Convert Arm Mali Utgard GPU to DT schema

Convert the Arm Utgard GPU binding to DT schema format.

'allwinner,sun8i-a23-mali' compatible was not documented, so add it.

The 'clocks' property is now required. This simplifies the schema as
effectively all the users require 'clocks' already and the upstream
driver requires clocks.
