[PATCH 1/2] ACPI: platform_profile: Stub platform_profile_cycle

[Janne Grunau via B4 Relay]

From: Janne Grunau <j@xxxxxxxxxx>

This is required to allow USB/Bluetooth HID devices to cycle through
platform profiles without depending on ACPI. Commit 52572cde8b4a4
("HID: lenovo: select CONFIG_ACPI_PLATFORM_PROFILE") added this
dependency for hid-lenovo which is used for external USB and Bluetooth
devices.

Fixes: 52572cde8b4a4 ("HID: lenovo: select CONFIG_ACPI_PLATFORM_PROFILE")
