arm: omap3: twl: remove usb phy init data

commit dbc98635

 ("phy: remove the old lookup method") removes
struct phy_consumer but twl-common.c still uses the "phy_consumer"
structure resulting in the following compilation warning.

arch/arm/mach-omap2/twl-common.c:94:21: error: array type has
incomplete element type
 struct phy_consumer consumers[] = {

Removed using phy_consumer since twl4030 uses the new lookup
method.
