The commit "HID: lenovo: Support for ThinkPad-X12-TAB-1/2 Kbd Fn keys"
introduced an issue where the CI failed with the following error:
ERROR: modpost: "platform_profile_cycle" [drivers/hid/hid-lenovo.ko] undefined!

This issue occurs because platform_profile_cycle is used without ensuring
the kernel is configured with CONFIG_ACPI_PLATFORM_PROFILE.
To address this, this patch adds conditional support for platform profile
management to the Fn+F8 key handling.
The functionality for platform_profile_cycle is now included only when
CONFIG_ACPI_PLATFORM_PROFILE is enabled in the kernel configuration.

This ensures compatibility with kernels that do not include the ACPI
platform profile feature, resolving the CI build issue.
