Add support for the Winbond W25Q32JW-xM flashes. These have a programmable QE bit. There is also the W25Q32JW-xQ variant which shares the ID with the W25Q32DW and W25Q32FW parts. The W25Q32JW-xQ has the QE bit hard strapped to 1, thus don't support the /HOLD and /WP pins. This was tested in single, dual and quad mode on a custom board with the NXP FlexSPI controller. Also the BP bits as well as the TB bit were tested.
