pflash: Clean up after commit 368a354f02b, part 2
Our pflash devices are simplistically modelled has having "num-blocks" sectors of equal size "sector-length". Real hardware commonly has sectors of different sizes. How our "sector-length" property is related to the physical device's multiple sector sizes is unclear. Helper functions pflash_cfi01_register() and pflash_cfi02_register() create a pflash device, set properties including "sector-length" and "num-blocks", and realize. They take parameters @size, @sector_len and @nb_blocs. QOMification left parameter @size unused. Obviously, @size should match @sector_len and @nb_blocs, i.e. size == sector_len * nb_blocs. All callers satisfy this. Remove @nb_blocs and compute it from @size and @sector_len.
