Subject: [PATCH] command: Use a constant pointer for the help
This text should never change during execution, so it makes sense to
use a const char * so that it can be declared as const in the code.
Update struct cmd_tbl with a const char * pointer for 'help'.
We cannot make usage const because of the bmode command, used on mx53ppd
for example.
