The application may need to read/write/erase the flash memory, but we not want console users to do so. This CL adds CONFIG_FLASH_PHYSICAL, which allows the higher-level CONFIG_FLASH to be undefined while still providing the chip-specific flash_physical_* accessor functions. There aren't many board.h files that needed changes, since CONFIG_FLASH_PHYSICAL is enabled by default, just like CONFIG_FLASH. BUG=chrome-os-partner:57408 BRANCH=none TEST=make buildall; try on Gru with and without CR50_DEV=1 See that it still boots, updates, wipes, restores, etc. without linking common/flash.o in the production image; and that the flash commands are still there in the dev build.
