[SeaBIOS] [PATCH] DSDT: Fix HPET _CRS Method

[Gabriel L. Somlo]

Updated _CRS method for HPET, bringing it in line with the way it is
presented on recent hardware (e.g. Dell Latitude D630, MacPro5,1, etc);
Allows it to be detected and utilized from Mac OS X; Also tested OK on
Linux (F16 64-bit install DVD) and Windows (Win7 64-bit install DVD).
