[media] dw2102: i2c transfer corrected for yet another cards



Related to Acorp DS120 and some revisions of DVBWorld DW2102.
If you read three or more registers at one time, you get wrong value for third etc.
Actually, it didn't affect the driver as it reads registers only by one at a time.
But it needs to correct.
