[Paul Menzel (Code Review)]

Hello build bot (Jenkins), Angel Pons,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/39377

to look at the new patch set (#2).

Change subject: amd/agesa/hudson: Do not write to DMA1_RESET_REG

amd/agesa/hudson: Do not write to DMA1_RESET_REG

coreboot on the ASUS F2A85-M PRO hangs there. After removing it, it runs
