[v3] USB: add devicetree helpers for determining dr_mode and phy_type

Here's another round of the dr_mode/phy_type patches. I think they should
be ready for merging now. Greg, will you apply them should there be no
problems anymore?

Sascha

changes since v2:

- fix adding of GPL Header was in wrong patch
- add missing hunk for new file of.c

changes since v1:
- move phy specific of helper to drivers/usb/phy/of.c
- use strcmp instead of strcasecmp for matching property values
- change usb_phy_dr_mode to usb_dr_mode
- change USBPHY_INTERFACE_MODE_NA to USBPHY_INTERFACE_MODE_UNKNOWN
- add copyright header to new files
- chipidea: drop mdelay at end of PTS/PTW setup
- chipidea: implement lpm core type handling for PTS/PTW


The following changes since commit 7b8bc3aad0deabf3bc50cd2fe29bce29be5681fe:

  USB: chipidea: ci13xxx_imx: Remove sparse warning (2013-01-30 00:17:39 -0500)

  USB chipidea i.MX: use devm_usb_get_phy_by_phandle to get phy (2013-01-31 12:27:36 +0100)

----------------------------------------------------------------
USB Chipidea patches for v3.9

These add OF helpers for handling the dr_mode and phy_type property
and makes use of them in the chipidea driver.
