This series add support for the ST7571 LCD Controller.
It is a 4 gray scale dot matrix LCD controller that supports several
interfaces such as SPI, I2C and a 8bit parallell port.

This driver only supports the I2C interface, but all common parts could
easily be put into a common file to be used with other interfaces.
I only have I2C to test with.

The device is a little defiant, it tends to NAK some commands, but all
commands takes effect, hence the I2C_M_IGNORE_NAK flag.

Changes in v2:
- Reworked pretty much the whole driver to not use obsolete code.
- Use panel and timing bindings to specify resolution and panel size
- Link to v1: https://lore.kernel.org/r/20250402-st7571-v1-0-351d6b9eeb4a@gmail.com
