    Convert tests of pMga->Chipset to tests of single bit flags.
    
    Several places in the driver contain if-statements that test Chipset against
    several different values to determine what functionality to use.  Some of
    these tests, HALCHIPSETS in particular, test as many as 6 different values.
    This bloats the code size unnecessarilly.  Instead we cache the results of
    some of those tests in single bit flags stored in pMga.
    
    These changes are similar to some changes in the pci-rework branch.

    Fix bug #8666.  git-bisect for the win!
    
    Since && takes precedence over ||, put parenthesis around the || block to
    make all the operations associate in the intended manner.
