[coreboot] Asrock e350m1: sata disks not recognized

[Valentin]

Hello,

I've built coreboot for a asrock e350m1 mainboard before the weekend and 
with the current version SATA disks were not detected. Neither by 
SeaBIOS nor in a current Linux system booted from USB.

As previos versions worked just fine i narrowed it down to the commit 
94c47c0 [https://review.coreboot.org/c/coreboot/+/37703], it's the first 
commit that shows this problem.
It seems to me that the rrot cause is that since this commit
sb_Poweron_Init() for the sb800 isn't called anywhere, but I'm not sure 
about the right way to include it.
Could anyone help with that?

Thanks,
Valentin
