I don't see more devices will be included later. It should be ok to 
merge them into one.

I changed the name due to I find the 
TRM(https://github.com/sophgo/sophgo-doc/blob/main/SG2042/TRM/source/system-control.rst) 
call it "system control",  so I changed it in v8.

Which one do you prefer? I'm not sure if there are any requirements for 
this?
