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.
