ISSI31FL3733 driver (#3679)

Browse source 
* ISSI31FL3733 driver

- Addapted IS31 driver for the above driver

* fix my branch

* ISSI31FL3733 driver

- Inclusion of above ISSI led driver

* IS31fl3733 driver

- Added correct function for control registers

* Finalized support for ISSI31fl3733 led driver

- Finalized and tested driver.
- Modified i2c_master for arm due to declaration mistake.
- Fixed spaces/tabs in quantum.h file.
- Fixed spaces/tabs in common_features.mk file.
- Removed unnecessary includes from rgb_matrix.c file.
- Added local definitions for MIN and MAX macros in rgb_matrix.c file.
- Adjusted chevron effect.
- Added necessary define (RGB_3733_MATRIX_ENABLE) for makefile.
- Added necessary C define (ISSI3733) to aid with inclusion of the correct header file.
- Added documentation for the new driver.

* Driver structure update

- Changed rule includes to be more condensed (RGB_MATRIX_ENABLE = IS31FL3731) and (RGB_MATRIX_ENABLE = IS31FL3733)
- Updated documentation
- Reverted to the use of differently named functions for each driver and selecting the needed ones within rgb_matrix.c

* ISSI Drivers refractoring

- Moved issi drivers in a dedicated folder
- Updated documentation

* I2C library fix

I released the special pins incorrectly before. It is now fixed.

* STM32_I2C_USE_I2C1 is TRUE in the mcuconf.h file. Pins B6 and B7 are used
