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.
