google/{falco,peppy}/gma.c: Do not include non-existent "hda.h"

Commit 75c83870 (azalia: Shrink boilerplate) [1] removed the header
file `hda_verb.h`. This header is still included in the mainboard’s
`gma.c`, causing the following build error, when native graphics
initialization is enabled.

        CC         mainboard/google/falco/gma.ramstage.o
    src/mainboard/google/falco/gma.c:34:22: fatal error: hda_verb.h: No such file or directory

This was not caught, as native graphics initialization is not enabled
for the build tests.

It turns out that the array `mainboard_cim_verb_data` is not used in
`src/mainboard/intel/wtm2/hda_verb.h`, so fix the problem by removing
the inclusion.
