[PATCH v1 0/4] Merge redmi-wmi into bitland-mifs-wmi

[Mingyou Chen]

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.

To safely merge them without sacrificing the high-level platform profile
and hwmon infrastructure of the Bitland driver or breaking the fine-grained
AI button toggles from the Redmi driver, the unified driver transitions
its sparse-keymap matching to a 32-bit little-endian scancode layout.

Additionally, this series cleans up the redundant Kconfig/Makefile hooks,
updates the MAINTAINERS entry accordingly, and introduces a newly reported
mic-mute hotkey definition for Redmibooks.

Testing status:
- Fully regression-tested on native Bitland hardware.
- Redmi-specific logic blocks and mic-mute quirks are compile-tested only.
  Feedback from Redmibook hardware owners is highly appreciated.
