Subject: [PATCH v2] platform/x86: redmi-wmi: Add more hotkey mappings

This patch adds more Fn hotkeys (like Refresh rate toggle).
Additionally, remap the setup key from KEY_SETUP to KEY_CONFIG.
As KEY_CONFIG is supported by Desktop Environments for launching
system settings, whereas KEY_SETUP is often ignored by userspace.

Changes in v2:
- Dropped Fn Lock (KEY_FN_ESC) mapping to avoid potential user confusion.
- The Fn Lock state is handled internally by the EC and does not require
  a dedicated key event. (Suggested by Gladyshev Ilya)
- Link to v1: https://lore.kernel.org/r/20260125-redmi-wmi-hotkey-add-v1-1-d3e28568dd75@outlook.com
