Since dfu read/write operations needs to be flushed manually, writing to filesystem on MMC by thor was broken. MMC raw write actually is working fine because current dfu_flush() function writes filesystem only. This commit adds dfu_flush() to f_thor and now filesystem write is working.
This change was tested on Trats2 board.
