The banding filter ON/OFF is controlled via bit 5 of COM8 register. It
is attempted to be enabled in ov772x_set_params() by the following line.
ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, 1);
But this unexpectedly results disabling the banding filter, because the
mask and set bits are exclusive.
On the other hand, ov772x_s_ctrl() correctly sets the bit by:
ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, BNDF_ON_OFF);
The same fix was already applied to non-soc_camera version of ov772x
driver in the commit commit
