MLK-10086-2 ARM: imx6: add dts entries for hsic controller

- Add usbphy_nop, hsic uses nop phy driver
- Add anatop phandle, hsic needs to access anatop register to
change osc clock for different boards
- Add phy_type, hsic needs to config PHY parameters at portsc
- For imx6q-arm2 board, hsic has pin conflict with ethernet, we create a
  dedicated dts(imx6q-arm2-hsic.dts) for it with ethernet disabled, besides
  please make sure keep the line of data and strobe unchanged between board
  boots up and enable hsic controller.
