[0/6] mips: dts: ralink: update system controller nodes and its consumers

Hi all!

Ralinks SoCs have a system controller node which serves as clock and reset
providers for the rest of the world. This patch series introduces clock and reset
definitions for these SoCs. The clocks are registered in the driver using
a bunch of arrays in specific order so these definitions represent the assigned
identifier that is used when this happens so client nodes can easily use it
to specify the clock which they consume without the need of checking driver code.
For the resets the definitions are the reset related bits in reset register of the
system controller node. Users of this introduced definitions are DTS files. 
DTS files which are currently on tree are incomplete and out of date and will be 
properly updated with the ones that are in openWRT tree[0](which is the main project user
of these SoCs) somewhere in time. But I am also updating current on-tree files as user 
of these definitions only taking into account system-controller related stuff so 
the things make properly aligned on tree. This is as per previous attempt and discussion
of just adding definitions in this patch [1].

I'd like this series to go through kernel mips git tree if possible.

Thanks in advance for your time.

Best regards,
    Sergio Paracuellos
