Shawn:

Similarly to [mezz] this is a spin-off of SCU3 (AFAIU, original
submission incorrectly called it SCU2 ESB) ESB board support
originally found in [v0].

Original submission was done by Andrey Gusakov, but he is too busy on
other projects, so the honors of submitting this were delegated to me.

NOTE: RAVE SP ("zii,rave-sp-esb") node is technically supported by
upstream, but it needs some fixes from [rave-sp-fixes] to work
correctly. If you want me to drop that node until [rave-sp-fixes] is
merged, let me know.

NOTE: This patch is currently generated to be on top of [mezz], but
that can be easily change should it be accepted first

Changes since [v0]:

- Patch converted to be a standalone file not dependent on any
ZII-specific .dtsi

- Added RAVE SP node with all the children that are currently
supported by upstream

- Droppped ecspi2 node. That node didn't have any child devices in
[v0] because none of the chips connected to that bus are supported
upstream. This node can be added later once anything attached to it
has upstream drivers.

- Dropped i2c_gpio. That bus was originally added for RAVE SP related
prototyping and is unused in actual product.

- Various newline fixes pointed out in [v0]

- Most of then nodes should be sorted alphabetically (I might have
missed some)

- Collected Reviewed-by from Fabio (Fabio, I assumed you won't mind,
but let me know if you want me to drop it)
