[PATCH 2/7][RFC] OMAP4: Create board support for OMAP_4430SDP.

[Santosh Shilimkar <santosh.shilimkar@ti.com>]

This patch creates the bare minimal board files  to support
OMAP_4430SDP. Additinaly new omap44xx.h is created which contains
the base addresses for OMAP4430.File omap34xx.h is adapted to avoid
multiple definitions of common omap base address definitions.
