Pin control bulk changes for the v4.17 kernel cycle:

New drivers:

- Qualcomm SDM845: this is their new flagship SoC platform
  which seems to be targeted at premium mobile handsets.

- Renesas R-Car M3-N SoC.

- Renesas R8A77980 SoC.

- NXP (ex Freescale) i.MX 6SLL SoC.

- Mediatek MT2712 SoC.

- Allwinner H6 SoC.

Improvements:

- Uniphier adds a few new functions and pins.

- Renesas refactorings and additional pin definitions.

- Improved pin groups for Axis Artpec6.

Cleanup:

- Drop the TZ1090 drivers. This platform is no longer
  maintained and is being deleted.

- Drop ST-Ericsson U8540/U9540 support as this was never
  productified.

- Overall minor fixes and janitorial.
pinctrl: uniphier: add UART hardware flow control pin-mux settings

UniPhier SoCs have the following pins for hardware flow control of UART:
  XRTS, XCTS
and for modem control of UART:
  XDTR, XDSR, XDCD, XRI

The port number with the flow control is SoC-dependent.
