mtd: spi-nor: winbond: Fix locking support for w25q256jw
The Winbond w25q256jw device:
- Supports lock/unlock via SR.
- Has Top/Bottom (TB) protect bit.
- Uses Status Register bit 6 as the Top/Bottom (TB) protect bit.
- Supports four Block Protect (BP) bits.
Update the flash parameters by enabling SPI_NOR_HAS_LOCK, SPI_NOR_HAS_TB,
SPI_NOR_TB_SR_BIT6 and SPI_NOR_4BIT_BP. Without these flags, the locking
configuration is incorrect.
