Most of NXP (Freescale) i.mx USB part has HSIC support, in this series,
we add support for them, it should cover all imx6 and imx7d SoC.

Changes for v5:
- Delete the useless doc changes introduced by former patch revision. [Patch 4/4]

Changes for v4:
- Some code style improvements [Patch 3/4]
- Add HSIC example at dts [Patch 4/4]

Changes for v3:
- Delete the internal API ci_ehci_override_wakeup_flag, and just use
  register read/write APIs. [Patch 1/4, 3/4]
- Using dedicated API usbmisc_imx6_hsic_get_reg_offset to calculate
  offset for HSIC controller. [Patch 2/4]
- Improve the comments for binding-doc, and add the dts example [Patch 4/4]

Changes for v2:
- Compile error reported by kbuild robot [Patch 2/4]
- Comment from Frieder Schrempf about code structure [Patch 2/4]
- Comment from Fabio about adding example for pinctrl [Patch 4/4]
