The PSL Slice Error Register (PSL_SERR_An) reports implementation dependent AFU errors, in the form of a bitmap. The PSL_SERR_An register content is printed in the form of hex dump debug message. This patch decodes the PSL_ERR_An register contents, and prints a specific error message for each possible error bit. It also dumps the secondary registers AFU_ERR_An and PSL_DSISR_An, that may contain extra debug information. This patch also removes the large WARN message that used to report the cxl slice error interrupt, and replaces it by a short informative message, that draws attention to AFU implementation errors.
