HID: lenovo: Use KEY_PERFORMANCE instead of ACPI's platform_profile

Commit 84c9d2a968c82 ("HID: lenovo: Support for ThinkPad-X12-TAB-1/2 Kbd
Fn keys") added a dependency on ACPI's platform_profile. This should not
be done for generic USB devices as this prevents using the devices on
non ACPI devices like Apple silicon Macs and other non-ACPI arm64
systems. An attempt to allow using platform_profile on non-ACPI systems
was rejected in [1] and instead platform_profile was made to fail during
init in commit dd133162c9cf ("ACPI: platform_profile: Avoid initializing
on non-ACPI platforms").
So remove the broken dependency and instead let's user space handle this
keycode by sending the new KEY_PERFORMANCE. Stable backport depends on
commit 89c5214639294 ("Input: add keycode for performance mode key").
