[Docs] Random Fixes (#8340)

* fix CLI section links in the Summary

* fix heading in Pointing Device doc

* fix headings in PS/2 Mouse Support doc

* add explicit section ids to I2C Master Driver doc

* reformat GPIO Controls table

Much like the I2C Master Driver doc, I found this a bit less than ideal to read. (The table was actually wider than the space available for it.)

Reformatted so each GPIO function is an H3 heading, followed by a paragraph and a table of each architecture's old-style function.

* migrate changes from I2C Master Driver doc to Japanese translation

* add explicit anchors to I2C Master Driver docs

* fix code block language markers

The language markers are case-sensitive; using the wrong case means the syntax highlighting doesn't work.

Good: ```c
Bad: ```C

* restore Japanese I2C Master Driver doc to current master

Can't update the internal tracking references accurately until the changes to the English doc are committed to master.

* add explicit anchors to edited files

* change ChibiOS/ARM to ARM/ChibiOS

Because ARM/ATSAM is also a thing that exists.

* fix code block language markers again

Used the wrong markers in a few spots. Also these are apparently always supposed to be lowercase.

* add section anchors to cli.md

* restore table formatting on GPIO Control doc

* remove changes to _summary.md

 The QMK CLI makes building and working with QMK keyboards easier. We have provided a number of commands to simplify and streamline tasks such as obtaining and compiling the QMK firmware, creating keymaps, and more.

 The CLI requires Python 3.5 or greater. We try to keep the number of requirements small but you will also need to install the packages listed in [`requirements.txt`](https://github.com/qmk/qmk_firmware/blob/master/requirements.txt). These are installed automatically when you install the QMK CLI.

 Pointing Device is a generic name for a feature intended to be generic: moving the system pointer around.  There are certainly other options for it - like mousekeys - but this aims to be easily modifiable and lightweight.  You can implement custom keys to control functionality, or you can gather information from other peripherals and insert it directly here - let QMK handle the processing for you.

+# PS/2 Mouse Support :id=ps2-mouse-support
 
 Its possible to hook up a PS/2 mouse (for example touchpads or trackpoints) to your keyboard as a composite device.
 
 To hook up a Trackpoint, you need to obtain a Trackpoint module (i.e. harvest from a Thinkpad keyboard), identify the function of each pin of the module, and make the necessary circuitry between controller and Trackpoint module. For more information, please refer to [Trackpoint Hardware](https://deskthority.net/wiki/TrackPoint_Hardware) page on Deskthority Wiki.
 
 There are three available modes for hooking up PS/2 devices: USART (best), interrupts (better) or busywait (not recommended).

 If you're using a trackpoint, you will likely want to be able to use it for scrolling.

 To enable the feature, you must set a scroll button mask as follows:
