[v4,0/7] remoteproc: qcom_q6v5_mss: Add MSM8909 and MSM8953

Convert parts of the qcom,q6v5.txt binding documentation to a DT schema
(together with some DT fixes) in preparation of adding new compatibles
for MSM8909 and MSM8953. The schema can be easily shared between
MSM8916, MSM8974, MSM8909 and MSM8953 because they have almost the same
requirements. The other SoCs are quite different and are likely more
clearly described in separate DT schema(s) to avoid a lot of complicated
if statements.

Since there were some concerns about overlap with the more generic
(but also more complex) DT schema Sireesh made in [1], I've coordinated
with Sireesh for v3 and include his adjusted changes for MSM8953 here.

---
Changes in v4:
  - Address review comments from Krzysztof

Changes in v3:
  - Combine series with Sireesh's for MSM8953

Changes in v2:
  - Address review comments from Krzysztof
  - Drop "ARM: dts: qcom: msm8974: Disable remoteprocs by default"
    since Bjorn applied it already
