mtd/cfi_flash: fix write problems for Numonyx P33/30 32 MBit flashs
commit 54652991 Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads to problems for smaller versions of this chip e.g. the 32Mbit version with deviceid 0x16 on mgcoge. So move the code for this work around to an own function and check previously manufacturer id and device id to not break other flashes which don't need this work around.
