I've found a workaround (requires compiling own kernel, tested on 4.11 and r4.11rc1):
When configuring kernel (I used make menuconfig) disable following things:
Everything under device drivers/gpio support, especially:
memory mapped files/amd promontory support (GPIO_AMDPT)
and pci gpio expanders / amd 8111 gpio driver (GPIO_AMD8111)
but I've turned of everything to make sure nothing is using gpio.

device drivers / pin controllers / amd gpio pin control (PINCTRL_AMD)
Perhaps only one of them could be really necessary, but I didn't tested that.
System boots normally, no problems with journald and no weird messages from dmesg.
