[PATCH] hda-codec - Fix definition of AC_KNBCAP_DELTA to match spec

[PATCH] hda-codec - Fix definition of AC_KNBCAP_DELTA to match spec

[Andrew Paprocki]

AC_KNBCAP_DELTA is incorrectly defined as (1<<8). According to the Intel
HDA spec, this is bit 7 after AC_KNBCAP_NUM_STEPS which is a 0x7f mask.
