[PATCH v3 0/4] platform/x86: bitland-mifs-wmi: Xiaomi Book Pro 14 support

[Chris Taraszka <chris@miget.com>]

Four patches on top of Mingyou Chen's v15 "Merge redmi-wmi into
bitland-mifs-wmi" [1] for the Xiaomi Book Pro 14 (TM2424).

Kento was right about the mode map in v2 [2]. The firmware passes
SystemPerMode to Intel DTT, and the DTT tables in its data vault name
each mode and set its PL1 per power source. v2 was measured on AC only,
where 0x03 looks like a 37 W mode, but on battery 0x03 is the firmware's
Turbo mode, so v2's balanced was the fastest mode on battery: 54 W
measured on BIOS 0A0A.

v3 maps low-power, balanced and performance to 0x02, 0x09 and 0x04, and
patch 3 lets performance use 0x03 on battery, re-applied when the power
source changes.

Kento, two differences from your map: low-power sets 0x02, which selects
the same DTT tables as 0x0a without the dimming, and
performance picks 0x03 by power source rather than reading back whether
0x04 stuck, so it does not depend on which BIOS refuses 0x04 on battery.

The Fn+K patch [3] is now patch 4, since it changes the quirks entry
from patch 1.

Changes since v2:
- New mode map from the firmware's DTT tables (Kento)
- Drop Mingyou's Reviewed-by from patch 1, as the map changed
- New patch 3: separate performance value on battery
- Fold in the Fn+K patch [3] as patch 4
