Add USB PHY device tree support for R8A7790/Lager board

Hello.

Here's the set of 2 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20140924-v3.17-rc6' tag. Here we add the USB PHY device tree support on the R8A7790/Lager reference board. The patchset requires the USB PHY driver already merged by Kishon and Greg in order to work, so can be applied at last...

[1/2] ARM: shmobile: r8a7790: add USB PHY DT support [2/2] ARM: shmobile: lager: enable USB PHY

WBR, Sergei

Define the R8A7790 generic part of the USB PHY device node. It is up to the board file to enable the device.

Changes in version 4:
- refreshed the patch.

Changes in version 3:
- changed subnodes of the USB PHY node to be per-channel;
- changed "renesas,phy-select" property to "reg" in the subnodes, and thus added "#address-cells" and "#size-cells" properties to the parent node;
- moved "#phy-cells" property from the parent node to the subnodes, changing its value to <1>;
- refreshed the patch.

Changes in version 2:
- added subnodes to the USB PHY node;
- refreshed the patch.
