Here it all comes together.

This patch series enables support for MSM8976 and MSM8956 with all
the extra functionality that has been tested and sent upstream and
also adds support for the Sony Xperia Loire platform, including two
devices in the Loire project: the Xperia X (Suzu) and the Xperia
X Compact (Kugo).

That's only a subset of what I actually have in my hat.. I didn't
feel like sending the entire thing because the rest is not perfectly
clean yet (even if working, and we all know that "works != clean").

As for my entire local stuff, here I can successfully boot Android 10
with nice display and 3d on both smartphones.

So, this is composed of:
- A main device-tree for the MSM8976/56 SoC (*)
- Standard configuration for the PM/PMI8950 and PM8004, which are
  found on all (from what I know) MSM8976 and 8956 boards, since
  that seems to be the recommended hardware configuration from qcom
- A main device-tree for the Sony Xperia Loire project (**)
- Device specific device-trees for Loire Kugo and Loire Suzu. (***)

(*) The MSM8956 SoC is a "broken" MSM8976. It has got two *disabled*
    BIG cores and you can't preventively know which ones are enabled
    and which ones are not: there you only know that you've got two.
    So, you can get any combination of disabled cores (relative to
    cluster 1, it can be 0,1 or 1,2 or 2,3 or 0,3 or 1,3.. etc) on
    the chip that you own.
    After many trials on (various) downstream kernels and a number of
    devices, I have concluded that the only way to get both the enabled
    big cores up is to actually declare all four and let Linux error
    out on the disabled cores (and - of course - never use them), mostly
    because there doesn't seem to be any register that can be read for
    that purpose... may sound stupid, but ... eh :)

(**) The Sony Xperia Loire platform is composed of 3 devices with their
     specific region variants, specifically, two MSM8956 smartphones
     (Suzu, Kugo) and one APQ8056 smart projector (Blanc). All these
     devices reuse the same base board design, so I thought that it is
     just better to create a common DT for all of them, hence avoiding
     a whole lot of code duplication.
     P.S.: I don't know if I'll ever try to upstream the SmartLoire
           APQ8056 Xperia Touch projector. I hope to have time to do
           it as it's a great device and I really want to but, as of
           now, I can't make any promise about that specific device.

(***) These DTs are now very light, but they will contain some
      more nodes as I get more components upstreamed. For example, the
      X Compact (Kugo) smartphone has Type-C through the FUSB301 chip,
      which resides on i2c, a RGBC-IR sensor and a VL53L0 ToF, while X
      (Suzu) has just MicroUSB and none of these sensors.
      These devices also are of a different form factor, so they've got
      different displays but connected to the same power rails anyway.
