I was being overly paranoid and double-checking these numbers.  I
confirmed PMI8998 and PM8005 from the docs (yay!).  The PM8998 docs
didn't have this, but I confirmed that I was talking to PM8998 by
confirming it was on the right USID and and then printing out the
value at probe time.  All look good.

nit: It appears that the above table was previously sorted by SUBTYPE
ID.  Could you perhaps move your 3 new PMICs to the bottom to maintain
this?  Other than that, you can add my Reviewed-by if you would like
(not that I have _any_ real expertise on SPMI, so might not be worth
it).
