The PECI-over-eSPI implementation, like the legacy implementation, must
acknowledge when the transaction is done by clearing the bit in the
register.

Despite the darp9 supporting an RGB backlit keyboard, the keyboard
option was removed and it ships with a white-only LED backlit keyboard
instead. The keypad `/` still has the cycle symbol printed on it, so
replace the color cycling function with the keyboard brightness
function used by other white-only LED keyboards (the 14" TKL ones).

Replace the get+set logic with a step function to change the backlight
level for `K_KBD_BKL`.
Keyboards using a DAC have a different set of levels due to the
brightness difference between the keyboards.

Make `white_dac` functions work based on the DAC power level like the
other I2C and PWM mechanisms, instead of preset values from an array.

Existing FDAT values remain unchanged in their functionality.
New functionality is added to fill unused FDAT values.
FDAT values correspond to the following functionality:
- 0: Set brightness
- 1: Get brightness
- 2: Get backlight type (new)
- 3: Set color
- 4: Get color (new)
- 5: <unused>
- 6: Set brightness (duplicate)

Use RGBKB-DET# to determine the type of keyboard connected.
If a white keyboard is attached, always set the color to white, and
always return white for the color.

Limit PL4 based on AC state for all units, not just those with dGPUs.
This will allow setting standard values in coreboot.
