Grammatical fixes for GPIO Control doc (#4869)

Browse source 
* Grammatical fixes for GPIO Control doc

I found the Advanced Settings section to be poorly written.

* Commit suggestions from fauxpark

* Change first instance of "microcontroller" to match suggestion

# GPIO Control # GPIO Control
QMK has a GPIO control abstraction layer which is micro-controller agnostic. This is done to allow easy access to pin control across different platforms.

## Advance settings ## Advanced Settings
Each micro-controller can have multiple advance settings regarding its GPIO. This abstraction layer does not limit the use of architecture specific functions. Advance users should consult the datasheet of there desired device and include any needed libraries. For AVR the standard avr/io.h library is used and for STM32 the Chibios [PAL library](http://chibios.sourceforge.net/docs3/hal/group___p_a_l.html) is used.
