There has been a (rare) varint of Dragonboard 820c, utilizing Pro
version of the SoC, with the major difference being CPU and GPU clock
tables. Add a DT file representing this version of the board.
01:13:26.275: B - 417880 - 8996 Pro v1.x detected, Max frequency = 1.8 GHz

- * 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
- * P HSEC = Primary High Speed External Connector
- * S HSEC = Secondary High Speed External Connector
- * J14 = Camera Connector
- * TP = Test Points
- *
- * Line names are taken from the schematic "DragonBoard 820c",
- * drawing no: LM25-P2751-1
- *
- * 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.

At least it matches what is written in the LK sources (or in MSM8996 Device Revision Guide). The JTAG ID matches APQ8096SG, the bootloader identifies it as 8996 Pro.
