PATCH v2 1/1 ata: ahci-dwc: Remove not-going-to-be-supported code for Baikal SoC

As noticed in the discussion [1] the Baikal SoC and platforms are not going to be finalized, hence remove stale code.

v2: dropped YAML and regmap.h (Niklas)

 .../bindings/ata/baikal,bt1-ahci.yaml         | 115 ------------------

Bindings are separate patches though anything only deleting lines is automatic ack. ;)

Looks like you missed a few more cases:

Documentation/devicetree/bindings/bus/baikal,bt1-apb.yaml Documentation/devicetree/bindings/bus/baikal,bt1-axi.yaml Documentation/devicetree/bindings/cache/baikal,bt1-l2-ctl.yaml Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml

Not really, see below my answers.

These are not related to ATA subsystem.

Quoted 2 lines

Documentation/devicetree/bindings/i2c/snps,designware-i2c.yaml Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml

These were missed in the respective previous submissions. Hence for these will be two (or do you want a single? I think they will need different Fixes tags, perhaps) patch to remove.
