cpu/amd/agesa: Use common MRC_CACHE code to save S3 data
Use the common code to save data for fast boot or S3 resume.
An notable improvement that comes with this, is that the same 4K page
is not rewritten all the time. This prolongs the hardware's life.
TESTED on pcengines/apu1 and lenovo/g505s: S3 resume works fine.
