When M4 is booted by ROM, we have to enable RPMSG in kernel, so need
to select the -rpmsg.dtb. If M4 is not enabled, use default kernel dtb.

u-boot currently needs information from ATF to know if
OP-TEE os has been loaded.
this information is transmitted via bootargs.
this patch enables saving those bootargs into a structure.

Make sure that all devices that are powered up by uboot
are powered down before bringing up kernel.
Else the subsystem/device will never be powered down by SCFW even though
from the kernel's point of view it should be powered down.
Benefiting from power domain driver, We have implemented the function "power_off_pd_devices"
to power off all active devices. No need to explicitly power off them in board_quiesce_devices.

We met u-boot hang when booting from eMMC fastboot on QM/QXP boards.
The hang happens on u-boot accessing USB2 PHY for checking USB boot.
The root cause is when putting AP image (u-boot-atf.bin) in first container,
the USB2 PHY reset bit won’t be set in CONN SS by SCFW, because this SS has been
powered on by SC ROM.
In normal boot case, we won't meet such issue. Because we put u-boot-atf.bin in second
container and AP ROM will boot up for loading this binary. When AP ROM completes the
loading, it calls “misc_boot_status” API to power off the boot device and also power
off the CONN SS. Then when u-boot enables any the module in CONN, the CONN SS will power
on again by SCFW and set the USB2 PHY reset bit.
Since the clock settings are different in SC ROM and SCFW, so it is suggested to power off
CONN SS when booting is completed. In this patch, we check the g_ap_mu field in pass over
structure which is used to pass into from SC ROM to AP ROM. This field is set only when AP
image is included in the second container. If this field is not set, we suppose the booting
only uses SC ROM, then u-boot calls "misc_boot_status" at early stage to power off
boot device.
