The checks for musb->xceiv and musb->xceiv->set_power duplicate those in
usb_phy_set_power(), so there is no need of them. Moreover, not calling
usb_phy_set_power() results in usb_phy_set_charger_current() not being
called, so current USB config max current is not propagated through USB
charger framework and charger drivers may try to draw more current than
allowed or possible.

Fix that by removing those extra checks and calling usb_phy_set_power()
directly.

Tested on Motorola Droid4 and Nokia N900
