This patch adds the /omit-if-no-ref/ keyword to the pio nodes for
UART0 and UART3 pins of the R40 SoC, which would reduce the fdt size on
boards which do not use these UARTs.

The Forlinx OKA40i-C devboard makes use of UARTs 0,2,3,4,5 and 7 of the R40
SoC, of which UART 0 is connected to an RS232 converter, UART 5 routed to
an RS485 converter, and the rest broken out directly via labeled headers.
The board also contains a micro-SD slot connected to SDC3.
This patch adds settings to R40's pinmux node for those UARTs that were not
already mapped, which would allow us to make use of all available UARTs and
the micro-SD slot on this board in a further patch.

I'd put omit-if-no-ref there too

The OKA40i-C is a carrier/development board for the Forlinx FETA40i-C SoM
based on the Allwinner R40/A40i SoC.
This patch adds the relevant dt-binding documentation in preparation for
the next patch, which adds a devicetree for the SoM and board.

The FETA40i-C is a SoM by Forlinx based on the Allwinner R40/A40i.
SoM specifications:
- SoC: R40 or A40i
- PMIC: AXP221S
- RAM: 1GiB/2GiB DDR3 (dual-rank)
- eMMC: 8GB,
- Mates with carrier board via four 80-pin connectors (AXK6F80337YG).
OKA40i-C is a carrier board by the same manufacturer for this SoM,
whose main purpose is as a development board with a wide variety of
peripherals:
- Power: DC5V barrel or USB OTG or 4.2V Lipo battery
- Video out: HDMI, TV out, LVDS
- WiFi+Bluetooth: RL-UM02WBS-8723BU-V1.2 (802.11 b/g/n, BT V2.1/3.0/4.0)
- Ethernet: 10/100Mbps
- Storage: µSD, fullsize SD, eMMC (on SoM), SATA
- USB: 3 x USB2.0 Host (2 via hub, 1 native), 1 x USB2.0 OTG (micro-B)
- UART: RS232, RS485, 4 3.3v uarts (of which 2 have RTS/CTS)
- Other I/O: SPI x2, TWI, SDIO header, GPIO header, JTAG header
- Mini PCIe slot with sim holder for WLAN modem
- Smart card holder
- RTC (RX8010SJ)
- Two user LEDs
- Three user buttons (via KeyADC).
This patch adds a devicetree for the aforementioned SoM and devboard.
In order to reflect the modularity of this devboard and simplify adding
support for future hardware based on the same SoM, the devicetree is split:
Everything pertaining to the SoM itself is described in a separate .dtsi
file, which is included by the devboard's .dts.
