[PATCH v6 0/5] Merge redmi-wmi into bitland-mifs-wmi

[Mingyou Chen <qby140326@gmail.com>]

This patch series consolidates the standalone 'redmi-wmi' driver into the
'bitland-mifs-wmi' driver to eliminate code duplication and centralize
the maintenance of overlapping ACPI WMI event streams.

Bitland is the ODM manufacturer for various Xiaomi Redmibook models. Both
platforms share the exact same keyboard event stream WMI GUID
(46C93E13-EE9B-4262-8488-563BCA757FEF). While redmi-wmi previously parsed
the 4-byte payload as a bulk u32 scancode, bitland-mifs-wmi deconstructed
it into discrete type/id/value fields.

Redmi operations were not contained in this patch series, future reverse
engineering is required.

This series introduce a newly reported mic-mute hotkey definition for Redmibooks
and dropped the previous redmi-wmi driver.

I don't have a Redmi or other Bitland device. So I cannot work on the
real device.

Features are working properly on my device (Lecoo Bellator N176).

I leave the future reverse engineering work to the community.

I apologize for not participating in kernel development over the past month.
Sorry for the late reply.

v6:
Drop the wrong Redmi ops

v5:
Correct Xiaomi DMI vendor name

v4:
Map PLATFORM_PROFILE_PERFORMANCE to wmi performance mode if the device
doesn't support full-speed mode.
