Similar feedback as for the J721S2 PADCONFIG patch, see the discussion below,

https://lore.kernel.org/all/20230328114742.tnaa5hi3qm3rsgld@ecology/

As suggested by Nishanth, let us do a single fixup to avoid non-addressable
regions and fix the padconfig region size.

>From datasheet I can see that the addresses corresponding to WKUP_PADCONFIG13,
WKUP_PADCONFIG25 are missing for J784S4.
