[v3,00/32] ARM: dts: qcom: cleanup PMIC usage

While reviewing APQ8064 CPUFreq patchset, Konrad pointed out that PMICs
are not a part of SoC and as such do not belong to the per-SoC files.

Cleanup the way 32-bit Qualcomm platforms treat PMICs:

- Move SSBI PMICs to separate files (as a bonus merging two different
  instances of PM8921, benefitting both platforms).

- Include such PMIC files only from the board files, keeping SoC file
  generic.

- Move RPM regulator definitions to board files too. They do not belong
  to the SoC dtsi files for the same reason.

- Move PMIC-specific GPIOs and supply properties to individual board
  files.

Note, enabling DT schema triggers warnings for pmic:led@48 in
qcom-apq8060-dragonboard.dts. This node uses custom ('cm3605') trigger
to make the LED follow the state of the proximity / ALS device.
Previously [1] Rob pointed out that this is not the best way and the
device should be switched to `trigger-sources' instead. However as I do
not have this device, I'm not brave enough to introduce these changes.

Note2: DT binding changes are largely independent from the DTS changes,
they can be applied separately.

Changes since v2:
- Rebased on top of linux-next to fix conflict
- Picked up dt-bindings patches from old, not-fully merged series.
- qcom,pm8921-keypad: droped the no-autorepeat property (Rob, Dmitry)
- Moved qcom,ssbi to /bus/ (Krzysztof)

Changes since v1:
- To ease reviewing break cleanups from the  "split PMIC" patches
  (Konrad).
