[PATCH 1/2] pinctrl: imx6q: add DTE pinctrl items for mx6q uart

[Huang Shijie]

This patch adds two DTE pinctrl items for UART in mx6q.
  MX6Q_PAD_EIM_D27__UART2_RXD_DTE: set the RX/TX into DTE mode.
  MX6Q_PAD_EIM_D29__UART2_RTS_DTE: set the RTS/CTS into DTE mode.

If the uart want to work in DTE mode and enable the hardware flow control,
it must selects these two pinctrl items.
