V4L/DVB: DaVinci - Adding platform & board changes for vpfe capture on DM365

This patch adds following changes:-
	1) add sub device configuration data for TVP5146 used by vpfe capture
	2) registers platform devices for vpfe_capture, isif and vpss
	3) defines hardware resources for the devices listed under 2)
	4) defines clock aliase for isif driver
	5) adding setup_pinmux() for isif
