Update this uclass to support the needs of the Apollo Lake ITSS. It supports four operations. Move the uclass into a separate directory so that sandbox can use it too. Add a new Kconfig to control it and enable this on x86. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
