lindar: Update GPIO to match schematic

1. Update gpio setting base on lindar’s schematics,
2. Remove sensor's gpio and code (not support)
3. Remove volume button's gpio,because lindar doesn't support
4. Add lightbar port information into I2C port map configuration

BUG=b:161089195
BRANCH=none
TEST=make -j BOARD=lindar
