Hi,

Switch older Qualcomm SoCs to use MMIO-based method instead of syscon.

Not tested on hardware. Please kindly provide tests.

Changes since v1
================
1. Use existing qcom,tcsr-msm8974 compatible.
2. Fix few other TCSR syscon compatibles (new patches: ipq6018, msm8953,
qcs404, msm8996).
3. New patch: dt-bindings: mfd: qcom,tcsr: drop simple-mfd from IPQ6018
4. New patch: dt-bindings: mfd: qcom,tcsr: add QCS404

Dependencies
============
1. Context in bindings depends on:
arm64: dts: qcom: improvements to TCSR mutex in DTS
https://lore.kernel.org/linux-devicetree/20220817130342.568396-1-krzysztof.kozlowski@linaro.org/T/#t

2. The last five DTS commits (ARM and arm64) named "switch TCSR mutex to MMIO"
depend on driver support. The changes are not bisectable, just like
previously such changes were not bisectable:
https://lore.kernel.org/all/20200622075956.171058-5-bjorn.andersson@linaro.org/

Best regards,
Krzysztof
