[Keyboard] Add S7 Elephant Rev2 Support (#9398)

* Add S7 Elephant Rev2 Support

* Apply suggestions from code review

I tested the changes on my board as well, thanks for the suggestions!

* Added a default folder in the makefile so that this would no longer be a breaking change

+# S7 Elephant
+
+![S7 Elephant](https://i.imgur.com/CaHxKBJ.jpg)
+
+A high-end 70% custom keyboard designed and produced by [jacky](https://geekhack.org/index.php?action=profile;u=63864) from Geekhack.
+
+* Keyboard Maintainer: QMK Community
+* Hardware Supported: S7 Elephant
+* Hardware Availability: [The GB has ended with little chance to run again.](https://geekhack.org/index.php?topic=96434.0)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make s7_elephant/rev2:default
+
+To enter the bootloader, either short the pins on the PCB next to CAPSLOCK or the press the RESET button on the FN layer.
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
