[PATCH V2 1/3] reset: imx7: Support module build

Mon Jun 29 11:05:27 EDT 2020


Add module device table, author, description and license to support
module build, and CONFIG_RESET_IMX7 is changed to default 'y' ONLY
for i.MX7D, other platforms need to select it in defconfig.

Changes since V1:
	- make it default 'y' for SOC_IMX7D;
	- add module author, description;
	- use device_initcall instead of builtin_platform_driver() to support
	  module unload.
