Subject: [PATCH 0/2] Remove HID_LENOVO's dependency on ACPI

hid-lenovo supports external generic USB and Bluetooth devices and
should be buildable and usable on non-ACPI kernels and systems. Commit
84c9d2a968c82 ("HID: lenovo: Support for ThinkPad-X12-TAB-1/2 Kbd Fn
keys") added a hot key to cycle through power profiles using ACPI's
platform_profile. This resulted in adding a dependency on ACPI and
selecting CONFIG_ACPI_PLATFORM_PROFILE to fix build an link errors in
commit 52572cde8b4a ("HID: lenovo: select
CONFIG_ACPI_PLATFORM_PROFILE"). This is undesirable for HID drivers
supporting generic USB and Bluetooth devices. So instead stub the only
used function platform_profile_cycle() and relax the dependency.
