arm64: dts: qcom: sbc: Name GPIO lines
This names the GPIO lines on the APQ8016 "SBC" also known as the DragonBoard 410c, according to the schematic. This is necessary for a conforming userspace looking across all GPIO chips for the GPIO lines named "GPIO-A" thru "GPIO-L".

/*
|

* GPIO name 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)
|
||||
* LSEC = Low Speed External Connector
|
||||
* HSEC = High Speed External Connector
|
||||
*
|
||||
* Line names are taken from the schematic "DragonBoard410c"
|
||||
* dated monday, august 31, 2015. Page 5 in particular.
|
||||
*
|
||||
* 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
|
||||
* UART3. 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.
