Fix for the Split Common I2C code's SCL_CLOCK issue (#3474)

* Fix the SLC_CLOCK setting for the Split Common code

Make the SCL_CLOCK setting configurable per board, since some use different settings
And change the Iris  to use 100000L instead of 400000L

* Add SCL_CLOCK variable to documentation

* Change SCL_CLOCK default to 100000L

 So you should use the `config.h` for QMK settings, and the `<name>.h` file for user or keymap specific settings.
 
+`/users/<name>/rules.mk` will be included in the build _after_ the `rules.mk` from your keymap. This allows you to have features in your userspace `rules.mk` that depend on individual QMK features that may or may not be available on a specific keyboard. For example, if you have RGB control features shared between all your keyboards that support RGB lighting, you can `define RGB_ENABLE` in your keymap `rules.mk` and then check for the variable in your userspace `rules.mk` like this:
+```make
+ifdef RGB_ENABLE
+    # Include my fancy rgb functions source here
+endif
+```
+Because of this, any time you turn on QMK features in your `users/<name>/rules.mk`, you should conditionally enable them only if the flag isn't already defined, like this:
+```make
+ifndef TAP_DANCE_ENABLE
+    TAP_DANCE_ENABLE = yes
+endif
+```
+This will ensure that you can explicitly turn off features for an individual keymap.

+![DC01 Arrow Cluster](https://i.imgur.com/PTn0sp8.jpg)
+
+A hotpluggable four part keyboard which comes together with magnets and pogo pins! This is the arrow cluster.
+
+Keyboard Maintainer: [Yiancar](https://github.com/yiancar)  
+Hardware Supported: Runs on an atmega32u4  
+Hardware Availability: [Mechboards](https://mechboards.co.uk/)  
+
+Make example for this keyboard (after setting up your build environment):

+# The default ANSI keymap for DC01 Left
+
+The keymap looks like a full layout keymap.
+
+This is because the left part of the keyboard acts as the masterm coordinating all four part.
+
+When using the keyboard to connect the other three parts, this keymap overwrites the individual keymaps of the single modules.
+
+When using a module individually, the keymap of that module will take effect.

+
+![DC01 Left Half](https://i.imgur.com/PTn0sp8.jpg)
+
+A hotpluggable four part keyboard which comes together with magnets and pogo pins! This is the left part that also acts as the master.
+
+Keyboard Maintainer: [Yiancar](https://github.com/yiancar)  
+Hardware Supported: Runs on an atmega32u4  
+Hardware Availability: [Mechboards](https://mechboards.co.uk/)  
+
+Make example for this keyboard (after setting up your build environment):
+
+    make dc01/left:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.

+![DC01 Right Half](https://i.imgur.com/PTn0sp8.jpg)
+
+A hotpluggable four part keyboard which comes together with magnets and pogo pins! This is the right part.
+
+Keyboard Maintainer: [Yiancar](https://github.com/yiancar)  
+Hardware Supported: Runs on an atmega32u4  
+Hardware Availability: [Mechboards](https://mechboards.co.uk/)  
+
+Make example for this keyboard (after setting up your build environment):
