[PATCH v2] ARM: shmobile: r8a7790: link PCI USB devices to USB PHY

[Sergei Shtylyov]

Describe the PCI USB devices that are behind the PCI bridges, adding necessary
links to the USB PHY device.

Based on the original work by Ben Dooks <ben.dooks at codethink.co.uk>.

This patch is against 'renesas-devel-v3.15-rc7-20140526' tag of Simon Horman's
'renesas.git' repo plus R8A7790/Lager PCI and USB PHY support patches posted
before. The patch requires the internal PCI DT support, USB PHY driver, and
USB HCD generic PHY support (also already posted) in order to work.

Changes in version 2:
- renamed the PCI OHCI/EHCI device nodes to comply with the PCI binding;
- changed the PHY specifier in the PCI#2 node to reflect that channel #1 support
  was dropped;
- resolved rejects, refreshed the patch.
