Subject: [PATCH drm/hisilicon v3 0/2] support reading resolutions from EDID 

patch #1 add a new file to implements i2c adapters, #2 read the
resolution from the edid, if that fails, set the resolution to fixed.
and update the destroy callback function to release the i2c adapters

Changes since v1:
-merge patch #3 into patch #2.
-add new function to_hibmc_drm_private, modify three functions in
hibmc_drm_i2c.c with the newly added function.
-deleting the member variable dev from the structure hibmc_connector.
-modify print log incorrectly.
-Modify hibmc_connector_get_modes.

Changes since v2:
-rewrite the function to_hibmc_drm_private, and rename GPIO_SCL_MASK
to I2C_SCL_MASK
