ARM: vf610: add auxiliary core boot support
Use i.MX bootaux support introduced for i.MX 6SoloX/i.MX 7 for
Vybrid too. Starting the Cortex-M4 core on Vybrid works a bit
differently, namely it uses a GPR register to define the initial
PC. There is no way to define the initial stack (the stack is
set up in a boot ROM). This is not a problem for most firmwares
since the firmwares startup code reinitialize the stack as part
of the firmware startup code anyway.
