[PATCH] platform/x86: ideapad-laptop: Map Smart Connect hotkey to KEY_LINK_PHONE

[Marco Giunta]

On certain 2025 Lenovo laptops, such as the Yoga Pro 7 14ASP10 and Legion
Pro 7 16AFR10H, the F11 key includes a symbol showing a laptop, a tablet
and a smartphone. According to the user manual, the key starts the Lenovo
Smart Connect app, which connects the laptop to phones and tablets.

These laptops send WMI hotkey event 0x48 (scancode 0x148) when the key
is pressed, which is currently reported as KEY_UNKNOWN. Map it to
KEY_LINK_PHONE as the closest match, as thinkpad_acpi does for the
Microsoft Phone Link and Intel Unison keys, see
commit 7ba618e893a4 ("platform/x86: thinkpad_acpi: Add support for new
phone link hotkey") and commit b511bbfe4242 ("platform/x86: thinkpad_acpi:
handle HKEY 0x1402 event").
