MLK-16005-1 drivers: soc: refine the imx8 soc revision support

This patch is to refine the imx8 soc revision support. The imx8qm and
imx8qxp will go through the SCU API to get the silicon ID and REVISION.
imx8mq will go through the anatop interface to get the ID/REV.

Since the silicon ID/REV need be set as early as possible, thus refine it
by using the early_initcall for the early initialization. For the SCU API
interface, this need be called after the MU interface initialized.
