Subject: [PATCH] usb: Fix compile error by selecting USB_OTG_UTILS

The current lpc32xx_defconfig breaks like this, caused by recent phy
restructuring:

  LD      init/built-in.o
drivers/built-in.o: In function `usb_hcd_nxp_probe':
drivers/usb/host/ohci-nxp.c:224: undefined reference to `isp1301_get_client'
drivers/built-in.o: In function `lpc32xx_udc_probe':
drivers/usb/gadget/lpc32xx_udc.c:3104: undefined reference to
`isp1301_get_client' distcc[27867] ERROR: compile (null) on localhost failed
make: *** [vmlinux] Error 1

This patch fixes this by selecting USB_OTG_UTILS in Kconfig which
causes the phy driver to be built again.

Signed-off-by: Roland Stigge <stigge@...com.de>
