This brings over the few know-how items and little things
I found about the BCMBCA LEDs in my previous duplicate driver.

This was tested on the BCM6846-based Genexis XG6846B.

The main addition is the ability to define the number shifting
bits in the serial shift register which is necessary if the
previous boot stages have not set up the hardware properly
before.

Changes in v4:
- Rebase on v6.12-rc1
- Add define for BCM63138_GLB_CTRL_SERIAL_LED_CLK_POL
- Rename the BCM63138_POWER_LUT to BCM63138_POWER_LUT_BASE0
- Link to v3: https://lore.kernel.org/r/20241004-bcm63138-leds-v3-0-ba99a8e464b9@linaro.org

Changes in v3:
- Mention in the DT binding that hardware defaults will be used if the
  property is missing.
- Link to v2: https://lore.kernel.org/r/20240928-bcm63138-leds-v2-0-f6aa4d4d6ef2@linaro.org

Changes in v2:
- Drop the u32 $ref in the schema, -bits is a standard suffix.
- Fix algorithm for shift register configuration.
- Fix spelling errors and numbering errors.
- Link to v1: https://lore.kernel.org/r/20240920-bcm63138-leds-v1-0-c150871324a0@linaro.org
