The fact that OPPs specified only on cpu0 work is Linux specific and
normally cpu frequencies should be specified for each cpu core.
To facilitate this without needing to duplicate the frequency table

Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.

Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.

Update cooling maps to include all devices affected by individual trip
points.

Add the power-domain nodes to both rk3066 and rk3188 including
their clocks and qos connections.
Signed-off-by: Heiko Stuebner <heiko@sntech.de>

QoS nodes keep information about priorites etc on the interconnect
and loose state when the power-domain gets disabled. Therefore the
power-domain driver stores the settings of available qos nodes and
restores them when the power-domain gets enabled again.

So add the qos nodes found on the Cortex-A9 socs from Rockchip, so
that they can then be connected to the power-domains.
