Following the existing naming convention in cputable.h, the features should
probably be amended to the following:

#define PPC_FEATURE2_ARCH_2_07      0x80000000
#define PPC_FEATURE2_HAS_HTM        0x40000000
#define PPC_FEATURE2_HAS_DSC        0x20000000
#define PPC_FEATURE2_HAS_EBB        0x10000000
#define PPC_FEATURE2_HAS_ISEL       0x08000000
#define PPC_FEATURE2_HAS_TAR        0x04000000

Notice that I changed DSCR to DSC.  The 'R' wasn't descriptive.
