[PATCH v8 3/3] ARM: shmobile: BOCK-W: add USB support

[Sergei Shtylyov]

Register the USB PHY device from bockw_init(), passing the platform  data to it.
Set machine's init_late() method to r8a7778_init_late() in order for [EO]HCI to
get registered too...

Don't forget to add USB PENC0/1 pins to bockw_pinctrl_map[].

The patch has been tested on the BOCK-W board.

Changes since version 6:
- added USB PENC0/1 pins to bockw_pinctrl_map[].

Changes since version 4:
- annotated 'usb_phy_platform_data' as '__initdata' since it's kmemdup()'ed
  while registering the platform device anyway;
- refreshed the patch.

Changes since version 3:
- removed initializer for 'usb_phy_platform_data' letting it be set to all 0s;
- refreshed the patch.

Changes since version 2:
- refreshed the patch.

Changes since the original posting:
- removed initializer for no longer existing field in 'usb_phy_platform_data',
  modified the comment to the 'ferrite_bead' field initializer.
