That does not look correct to me?  There is only a single
EFUSE bit being SELFPRGEN, however the part seems
to implement bits one and two, but they are not documented.

I'll submit the t88 config section later today after I get some more
time on it.  It is still only a 'best guess' being that the data sheet
is wrong in this area, seems to be a copy&paste from some other part.
