I notice that the umachine.Pin has a two class literals that Python would not allow

        5V_ENABLE : Any ## <class 'Pin'> = Pin("5V_ENABLE", mode=IN, pull=PULL_OFF, GPIO=PC14)
        3V3_ENABLE : Any ## <class 'Pin'> = Pin("3V3_ENABLE", mode=IN, pull=PULL_OFF, GPIO=PC15)

I'm not sure if this is new to the 1.20.0 build, or existed earlier
also not quite sure what PEP this violates , but names cannot start with a Digit , so perhaps change to ENABLE_5V instead ?

Also I notice that the umachine.uname() does not exist.
Is there any specific reason for that , or should it be enabled with #define MICROPY_PY_UOS_UNAME (1) ?
( the machine.name() issue is not new to 1.20.0)
