Manivannan Sadhasivam 1761101048 arm64: dts: hisilicon: hikey970: Add SD and WiFi support 
Add SD and WiFi support for HiKey970 board based on HI3670 SoC. Due to
the absence of the PMIC driver, fixed regulators are sourced to make the
driver working.

* Legend: proper name = the GPIO line is used as GPIO
* NC = not connected (pin out but not routed from the chip to
* anything the board)
* "[PER]" = pin is muxed for [peripheral] (not GPIO)
* "" = no idea, schematic doesn't say, could be
* unrouted (not connected to any external pin)
* LSEC = Low Speed External Connector
* HSEC = High Speed External Connector
*
* Line names are taken from "hikey970-schematics.pdf" from HiSilicon.
*
* For the lines routed to the external connectors the
* lines are named after the 96Boards CE Specification 1.0,
* Appendix "Expansion Connector Signal Description".
*
* When the 96Board naming of a line and the schematic name of
* the same line are in conflict, the 96Board specification
* takes precedence, which means that the external UART on the
* LSEC is named UART0 while the schematic and SoC names this
* UART2. This is only for the informational lines i.e. "[FOO]",
* the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
* ones actually used for GPIO.
