Drop the size parameter to indicate we need to do SFDP, we can do that because it is guaranteed that the size will be set by SFDP and because PARSE_SFDP forced the SFDP parsing it must be overwritten. There is a (very tiny) chance that this might break block protection support: we now rely on the SFDP reported size of the flash for the BP calculation. OTOH, if the flash reports its size wrong, we are in bigger trouble than just having the BP calculation wrong.
