[PATCH v4 0/2] spi: davinci: Convert bindings to DT schema and clean up DTS

[Bhargav Joshi <j.bhargav.u@gmail.com>]

This series converts the TI DaVinci/Keystone SPI controller device tree
bindings from the legacy text format to DT schema. 

- Patch 1 renames property ti,davinci-spi-num-cs from keystone-k2l.dtsi,
  as the driver uses the standard num-cs property.
- Patch 2 Converts ti,davinci-spi from text to DT schema.

Changes in v4:
- Fixed spacing in example.
- Fixed commit title.
- Rebasesd to latest mainline rc.
- Link to v3: https://lore.kernel.org/r/20260817-ti-davinci-spi-v3-0-23844cfb5e6a@gmail.com

Changes in v3:
- patch 2: since old text binding required num-cs, #address-cells, and
  #size-cells mark them as required
- patch 2: davinci-spi don't work as spi-slave i.e address-cells 0 is
  not applicable and spi-controller permits both 0 and 1 so explicitely
  define #address-cells as 1

Changes in v2:

- patch 1: Instead of deleting ti,davinci-spi-num-cs, renamed it to
  num-cs to properly preserve the hardware's intended chip select
  limits 
- patch 2: Removed  maximum: 6 constraint from num-cs.
- patch 2: Add standalone support for ti,dm6441-spi in compatibles.
