staging: exfat: add exfat filesystem code to staging

The exfat code needs a lot of work to get it into "real" shape for
the fs/ part of the kernel, so put it into drivers/staging/ for now so
that it can be worked on by everyone in the community.

The full specification of the filesystem can be found at:
  https://docs.microsoft.com/en-us/windows/win32/fileio/exfat-specification

This option should be set to the codepage of your exFAT filesystems.

Set this to the default input/output character set you'd like exFAT to use.

exfat_core.c - ffsReadFile - the goto err_out seem to leak a brelse().
same for ffsWriteFile.
exfat_core.c - fs_sync(sb,0) all over the place looks fishy as hell.
There's only one place that calls it with a non-zero argument.
ffsTruncateFile - if (old_size <= new_size) {
That doesn't look right. How did it ever work? Are they relying on lazy
block allocation when actual writes happen? If nothing else, it never
does the 'fid->size = new_size' and do the inode update....
ffsSetAttr() is just dangling in the breeze, not wired up at all...
