MLK-12531 mx6sxsabresd: Add CM4 fast boot up demo
This is a demo that CM4 will boot up by u-boot without typing any
command. It boots up at u-boot early init, try to minimize the time
from power up to the CM4 running.
Since CM4 runs on QSPI NOR XIP, we have to disable the QSPI driver in
u-boot to avoid conflict.
RDC for shared GPIO1 is added, but not enabled, because the kernel is
not ready for shared GPIO1. Users can uncomment the CONFIG_IMX_RDC to
enable it.
Some legacy codes in mx6sxsabreauto are removed. We only need this work
on mx6sxsabresd as a demo.
