MA-12335 Canonical Boot Reason in Android Pie 9.0
Read boot reason from SRC(system reset controller) and report
it to kernel by "androidboot.bootreason=<>" kernel commandline.
This is enabled on imx6/7/7ulp/8m, imx8 will report default value
"androidboot.bootreason=reboot" since it can't get such info on
A core at u-boot stage.
Test: Boot reason report ok on imx6qp/imx7ulp/imx8qxp.
