imx: set CPU boot entry for partition reboot

With SPL running on OCRAM, when linux suspend, OCRAM
will lose power and if partition reboot is started from
SPL, system will hang as the OCRAM data lost, so for
partition reboot, the CPU boot entry can be set to
be from ATF BL31 entry directly, SCFW exposes such API
for this scenario.
