Subject: [PATCH v3 13/15] drm/i915/dsi: Prepare soc_gpio_set_value() to distinguish GPIO communities

Currently soc_gpio_set_value() supports only a single indexing for GPIO pin.
For CHV case, for example, we will need to distinguish community based index
from the one that VBT is using. Introduce an additional parameter to
soc_gpio_set_value() and its callers.
