mb/google/dedede/var/bugzzy: Update GPP_D5 configuration
As we checked the panel doesn't display firmware screen if we hold
GPP_D5(TOUCHSCREEN_RESET) low on bugzzy. It's because of that bugzzy
uses the built-in touch screen on the panel, the panel seems like
under reset state by the TOUCHSCREEN_RESET signal.
This change sets default GPP_D5 level to high for bugzzy.
BUG=b:None
BRANCH=dedede
TEST=built and verified bugzzy showed firmware screen
