[PATCH 3/6 v2] OMAP4: Re-arrange the low level debug code

[Santosh Shilimkar]

On OMAP4430 the UART3 base address is different than that on OMAP3.
Because of this existing code needs additional #ifdef'ry to accommodate
that code. Hence this patch separates it. Also UART3 base address is
fixed for OMAP4430 in this patch.
