platform/x86: acerhdf: restructure to allow large BIOS table be __initconst
There is a table of Vendor/Model/Version {control data} in this driver, but outside of the initial probe, the V/M/V is never used again, and neither are any of the entries for platforms other than the one which matches the running target. By simply storing the {control data} for the matched platform, we can mark the large table __initconst, which reduces the loaded driver size by 20 percent.
