bis: Pull latest lockpick driver and refactor it
- Refactor various variables and functions - Flush whole cache when full - Allow cache to be disabled - Add support for raw emuMMC in nyx contenxt - Use partition names for keys (to avoid issues with different ordering) - Add deinit function that flushes the whole cache - Change bis lookup address - Halve cache size to 256MB in order to support 512MB ramdisk also.
