HID: lenovo: Remove CONFIG_ACPI dependency

The hid-lenovo driver supports external Bluetooth and USB devices which
can be used with non-ACPI systems/kernels. Call platform_profile_cycle()
only if CONFIG_ACPI_PLATFORM_PROFILE is enabled and select
CONFIG_ACPI_PLATFORM_PROFILE only if ACPI is enabled.
This should not affect functionality since only the detachable keyboard
of a x86 tablet with a custom connector has an hotkey for cycling
through power profiles.
