ARM: dts: logicpd-torpedo: Add isp1763 support to baseboard

The baseboard has an ISP1763 USB controller acting as a host.
Since the pinmuxing for the corresponding IRQ is different
between OMAP35 and DM37, the pinmux has been placed in the
kit-level files, while the common code is placed into the
baseboard file.
