arm64: dts: bitmain: Add GPIO Line names for Sophon Edge board
Add GPIO line names for Sophon Edge board based on BM1880 SoC from Bitmain. Line names are based on the board schematics as well as the 96Boards Consumer Edition specification v1.0.

/*

|
* 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 "sophon-edge-schematics"
|
||||||
|
* version, 1.0210.
|
||||||
|
*
|
||||||
|
* 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. 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.
