[PATCH v1] platform/x86: redmi-wmi: add display-switch key binding

[Ilya Gladyshev]

As reported on the mailing list [1], on the Xiaomi Redmi Book Pro 16
2024, the display-switch key emits 0x101 as a WMI payload. Add a
mapping for it to the keymap.

This patch conflicts with the unification of redmi-wmi and
bitland-mifs-wmi [2]. However, that patch appears to be stuck for now,
so updating a single mapping in the old driver seems acceptable.

Cc its author, Mingyou Chen.

Also, I can only test that it doesn't break on my hardware, so any
additional testing is highly welcome.
