imx9: allow to bootaux Mcore with input address

Browse source 
Currently bootaux only supports to boot M33 core from TCM. Since ATF
has changed to use x2 parameter for M33 image address, update the
bootaux command to use input address, so we can support boot from
any possilbe address like TCM, DDR, Flexspi NOR.
