mb/google/nissa/var/sundance: Change touch panel and wwan gpio setting
In order to fit the specification, change gpio setting for touch panel and wwan. Change items: 1. wwan : Add WWAN_RST_L to 0. And we want WWAN_EN to pull high more early than WWAN_RST_L, so add WWAN_EN to 1 in romstage stage. 2. touch panel : First we add EN_PP3300_TCHSCR and USI_RST_L to 0 to init status. And we want EN_PP3300_TCHSCR to pull high more early than USI_RST_L so delete USI_RST_L pull high in romstage.
