All beagle boards rev > AX/BX have external usb hubs connected to ehci
interface, external hub/peripheral uses a nreset sequence for which
uart2_rx.gpio_147 pin in mux mode4(USB2HS_nRST) is used on all beagle
boards expect rev Ax/BX.
(Reference to all beagle boards rev schematics:
http://beagleboard.org/hardware/design)

Initialising uart2 will lead to serial init taking over uart2_rx pin
so init uart2_rx pin mux only for Beagle AX/BX rev boards.
Dont init uart2 for all other boards allowing usb_ehci functionality.

To initialise individual uart port by id utilise and modify the existing
available func. omap_serial_board_init.
