Revert "of: reserved-memory: Fix using wrong number of cells to get property 'alignment'"

Browse source 
This reverts commit 267b21d0be.

Turns out some DTs do depend on this behavior. Specifically, a
downstream Pixel 6 DT. Revert the change at least until we can decide if
the DT spec can be changed instead.
