staging: west bridge: cyasgadget, remove file system / vfs calls
This patch remove file system specific (fat_get_block) and vfs calls
from the cyasgadget driver. The current implementation expects user
space to write the file (open, seek to end, 1 byte write), followed by a
call to clear the dirty pages from the the page cache.
