Subject: [PATCH v4] platform/x86: huawei-wmi: add keys for HONOR models

HONOR MagicBook X16/X14 models produced in 2025 cannot use
the Print Screen and YOYO keys properly, with the system
reporting them as unknown key presses (codes: 0x028b and 0x028e).

To resolve this, the key_entry is added for both the
HONOR Print Screen key and the HONOR YOYO key, ensuring
they function correctly on these models.
