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
