Add support for frobbing Intel StrataFlash Protection Registers:
o add CFI_SUPPORT_STRATAFLASH compile option to enable support o add new ioctls to get/set the factory and user/oem segments of the PR and to get/set Protection Lock Register that fuses the user segment o add #defines for bits in the status register o update cfi_wait_ready to take an offset so it can be used to wait for PR write completion and replace constants w/ symbolic names Note: writing the user segment isn't correct; committing now to get review.
