modules/fatfs: Move FATFS Zephyr specific code and cmake The code moves Zephyr specific code and CMakeLists.txt under modules/fatfs/. The commit also adds zephyr_fatfs_config.h header file, that is now used to override FF_ options of ffconf.h file within fatfs repository. Signed-off-by: Dominik Ermel <dominik.ermel@nordicsemi.no>

fs/fatfs: Move FF_USE_LFN logic to Kconfig Commit add hidden Kconfig option CONFIG_FS_FATFS_FF_USE_LFN that is passed to ELM FAT to define FF_USE_LFN configuration. The FF_USE_LFN still depends, indirectly, on choice CONFIG_FS_FATFS_LFN_MODE config options CONFIG_FS_FATFS_LFN_MODE_BSS, FS_FATFS_LFN_MODE_STACK and FS_FATFS_LFN_MODE_HEAP, but the logic has been moved out of zephyr_fatfs_config.h into Kconfig file.

fs/fatfs: Add CONFIG_FS_FATFS_MIN_SS The Kconfig option allows to set minimum expected sector size to be supported by FAT fs driver. When this value differs from CONFIG_FS_FATFS_MAX_SS the driver will query device for actual sector size, expecting different sector sizes for different device. When CONFIG_FS_FATFS_MIN_SS and CONFIG_FS_FATFS_MAX_SS are the same, then there is slight reduction if FAT driver size, as the query logic is removed and CONFIG_FS_FATFS_MAX_SS is used for all devices.
