This series adds in MSM8939 SoC support with two supported devices.

- CPU
  MSM8939 is a non-PSCI compliant device. As such in the downstreaming
  shipped image custom code is used to bring non-boot cores out of reset.

  This drop specifies the boot-method as spin-table instead and is
  completely standard. To accomplish this, we rely on lk2nd.

  https://github.com/msm8916-mainline/lk2nd/pull/142

- Serial
- i2c
- USB
- eMMC
- MDP/DSI
- WiFi
- Bluetooth

What's not included 

- CPR
  We have CPR working in a 4.19 kernel quite well but for now it feels like
  putting the cart before the horse to gate the SoC and boards on CPR.

- Venus
  I've been told this works but I haven't tried it myself and right now
  consider it maybe working but probably not 100%.

- Sound
  We have a copy-exactly from the 4.19 kernel here in the DTS.
  I haven't run the sound through any sort of reasonable test.
  Vincent Knecht has some PostmarketOS kernels which use a 5.17 version of
  this DTS to get sound up so, I think sound is in good shape.

- CAMSS
  There are slight differences between msm8916 and msm8939 for CAMSS. It
  doesn't feel like tons of work but, right now it is work we haven't even
  started.

- Devices
  I've booted on the Square device obviously and this is my regular
  hardware for upstream development. I've also booted on the Sony Xperia M4
  Aqua including mutli-core bring-up, WiFi and ADB.
