[PATCH 1/2 v5] ARM: dts: add EBI2 to the Qualcomm MSM8660 DTSI

[Linus Walleij]

This adds the external bus interface EBI2 to the MSM8660 device
tree, albeit with status = "disabled" so that devices actually
using EBI2 can turn it on if needed.

ChangeLog v4->v5:
- Rename "ebi2@" to "external-bus@"
- Can we apply this now?
ChangeLog v3->v4:
- Rebase on kernel v4.9-rc1
- Bindings and driver are merged so should be clear to apply.
ChangeLog v2->v3:
- Use the new #address-cells = <2> for indicating the CS in the
  first address cell
- Use the ranges property properly for defining the six different
  CS address windows
- Define CS3 to properly map over 128MB
- The EBI2 bindings are now ACKed by Rob Herring and a pull request
  to ARM SoC for both binding and driver is pending.
- This should be safe to merge for v4.9
