google/poppy: Set GPIO GPP_D22 high 

same change as I49935e659bf67225d3f5db1b06acc2cd046dcd74
this is required for poppy board as well.

GPIO GPP_D22 controls the I2S buffer for isolating the I2S signals
when doing GPIO-driven I2S.  This needs to be high by default so
the DSP can drive these signals, instead of low where it is enabled
for GPIO-driven I2S and the DSP cannot drive these signals.

BUG=None
BRANCH=None
TEST=play test sound in OS over internal speaker
