MUSB on OMAP3EVM uses ISP1504 phy and doesn't need twl4030.
OMAP35xx Beagle board MUSB uses twl4030 phy thus uses it and
it also sets xceiv global field using otg_set_transceiver().
As OMAP3EVM MUSB doesn't require twl4030 so otg_set_transceiver()
part is being done in this patch.
This is a temporary patch and the updated patch will come soon.
