omap: 3630sdp: introduce 3630 sdp board support

Add 3630SDP board support

The board shares the same peripherals as a zoom2 main.
So reuse the peripheral file of zoom platform.

Peripheral    zoom2    zoom3  sdp3630
---------------------------------------
Ethernet	smsc	smsc	smc
NOR		n/a     n/a	B
Onenand	  	n/a     n/a	B
HDMI		A	A	B (persent on different i2c)
NAND		A	A	A (same nand)
SDRAM		A	A	A (same sdram)
Keypad		A	A	A (same twl)
Camera		A	A	A (same sensor can be mounted)
LCD Display	A	A	A (same wvga display)
OPPs		A	A	A (same chip feature)
Audio		A	A	A (same audio via twl5030)
