Change subject: drivers/spi/winbond: Add function to lock flash's status register
......................................................................


Patch Set 1:

Tested on Winbond W25Q128.
Status register lock bits can be written multiple times until this method is called.
All following calls will fail, as the status register bits won't change any more.
