MIT licensed FreeRTOS is Detected as GPL-2.0-or-later WITH freertos-exception-2.0

[JustinWonjaePark]

Description

A lot of scanning output FreeRTOS v10.0.0 contains "GPL-2.0-or-later WITH freertos-exception-2.0"
When you look into the files, you can find MIT License text with some FreeRTOS name and url appearing.
Example : https://github.com/FreeRTOS/FreeRTOS-Kernel/blob/V10.0.0/FreeRTOS/Source/list.c

How To Reproduce

Scan FreeRTOS v10.0.0 https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/V10.0.0
Or, you can just scan /FreeRTOS/Source directory to simply reproduce.

The command I ran is:
scancode scancode -clip --json-pp - > scan.json ../../FreeRTOS-Kernel-10.0.0/FreeRTOS/Source

Result : scan.json

System configuration

For bug reports, it really helps us to know:

• What OS are you running on? MacOS
• What version of scancode-toolkit was used to generate the scan file? 32.2.1
• What installation method was used to install/run scancode? pip

The license text at https://github.com/FreeRTOS/FreeRTOS-Kernel/blob/V10.0.0/FreeRTOS/Source/list.c
is a slight variation on the standard MIT license and contains this unique text:
"If you wish to use our Amazon FreeRTOS name, please do so in a fair use way that does not cause confusion."

New license freertos-mit added to DejaCode. Permissive. @AyanSinhaMahapatra please synchronize and thanks in advance! We should definitely be detecting this new license rather than the exception when we encounter this text.
