[PATCH V5 6/9] pinctrl: imx8mp: Support building as module

[Anson Huang]

Change configuration to "tristate", add module device table,
author, description and license to support building i.MX8MP
pinctrl driver as module.

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

Changes since V4:
        - remove unnecessary change of replacing arch_initcall() with 
module_platform_driver();
        - add module author and description;
        - add more details to commit message.
