[media] TVP7002: Changed register values

Register values changed according to the data sheet and Texas Instruments DaVinci_PSP_03_02_00_37.
	- TVP7002_RGB_COARSE_CLAMP_CTL changed to the default value in data sheet.
 	- TVP7002_HPLL_PHASE_SEL deleted because the registers write to reserved bits. The default value works fine.
