SPI NOR changes for 7.2

Notable changes:

- Big set of cleanups and improvements to the locking support. This series contains some cleanups and bug fixes for code and documentation around write protection. Then support is added for complement locking, which allows finer grained configuration of what is considered locked and unlocked. Then complement locking is enabled on a bunch of Winbond W25 flashes.

- Fix die erase support on Spansion flashes. Die erase is only supported on multi-die flashes, but the die erase opcode was set for all. When the opcode is set, it overrides the default chip erase opcode which should be used for single-die flashes. Only set the opcode on multi-die flashes. Also, the opcode was not set on multi-die s28hx-t flashes. Set it so they can use die-erase correctly.
