mtd: spi-nor: winbond: Fix locking support for w25q64jvm

The Winbond w25q64jvm supports block protection through the Status
Register (SR) and provides a Top/Bottom (TB) protection bit.

Enable SPI_NOR_HAS_LOCK and SPI_NOR_HAS_TB for this device to
properly describe its locking capabilities.

The device uses Status Register bit 5 as the TB bit and supports only
three Block Protect (BP) bits. Therefore, do not set SPI_NOR_TB_SR_BIT6
or SPI_NOR_4BIT_BP.
