Chuanhong Guo f0f35fdac1 Revert "generic: 5.4: Add 4B_OPCODES flag to w25q256"
This reverts commit d7f21940bcaf70ba404d354c7fa6519c1717d00a.

Winbond W25Q256FV and W25Q256JV both uses 0xef4019 as JEDEC ID,
but only the latter has proper 4B_OPCODES support.
W25Q256FV has all 4B read instructions but it lacks a 4B page program
instruction, causing the entire flash to be read-only.
