The value 0xC4000003 is no register, but a SMC call [0] function identifier, and part of the Power State Coordination Interface [1]. So 0xfffffffffffffff7 seems to be -9, which means INVALID_ADDRESS according to [1]. Looks like the provided ip is not ok? It has to be in the RAM below 0x40000000, isn't it?
I also had found the description for the PSCI and had started reading in it.
The address is indeed 0x4001003c. This parameter comes form the call in base-hw/src/bootstrap/spec/arm_64/cortex_a53_mmu.cc where wake_up_all_cpus() is called with the address of _crt0_start_secondary.
sorry, for my misleading wrong sentence. I meant it has to be _not_ below 0x40000000. And I was refering to the ARM Trusted Firmware sources, I found are the right one for the i.MX 8MQ EVK. For your SoC, I found the line[0] to be the relevant one for the ip checking.
The question arises what version of the ATF are you using. Did you compiled the bootloader chain yourself?

How can I influence where a function is placed? I see, that in base/src/ld/genode.ld the content from crt0 is integrated.
