Subject: [PATCH V5 6/6] clk: imx8qxp: Support building i.MX8QXP clock driver as module

Change configuration to "tristate", add module author, description and
license to support building i.MX8QXP clock drivers as module.

Signed-off-by: Anson Huang <Anson.Huang@....com>

Changes since V4:
	- keep using builtin_platform_driver();
	- add COMPILE_TEST support.
