Variable naming val and val1 has to match register macro naming;
historically, corresponding macros were named GEN6_PCODE_DATA and
GEN6_PCODE_DATA1. Since GEN6_PCODE_DATA has been renamed by spec to
GEN6_PCODE_DATA0, rename register macro to match spec and variable val
into val0 in functions declaring val1.

There's not a whole lot of point in sending patches that depend on other
patches, because you won't get CI results, and any review depends on the
other patch having been merged.
