MIPS: Alchemy: introduce helpers to access SYS register block.
This patch changes all absolute SYS_XY registers to offsets from the SYS block base, prefixes them with AU1000 to avoid silent failures due to changed addresses, and introduces helper functions to read/write them. No functional changes, comparing assembly of a few select functions shows no differences.
