Add Boot-Regions verification specified in exFAT specification.
Note that the checksum type is strongly related to the raw structure,
so the'u32 'type is used to clarify the number of bits.

Separate the boot sector analysis to read_boot_sector().
And add a check for the fs_name field.
Furthermore, add a strict consistency check, because overlapping areas
can cause serious corruption.

Optimize directory access based on exfat_entry_set_cache.
- Hold bh instead of copied d-entry.
- Modify bh->data directly instead of the copied d-entry.
- Write back the retained bh instead of rescanning the d-entry-set.
And
- Remove unused cache related definitions.

Doing copy_file_range() on exfat with a file opened for direct IO leads
to an -EFAULT:
-c "copy_range -d 16384 -l 16384 -f 0" /mnt/test/junk
copy_range: Bad address
and the reason seems to be that we go through:
default_file_splice_write
splice_from_pipe
__splice_from_pipe
write_pipe_buf
__kernel_write
new_sync_write
generic_file_write_iter
generic_file_direct_write
exfat_direct_IO
do_blockdev_direct_IO
iov_iter_get_pages
and land in iterate_all_kinds(), which does "return -EFAULT" for our kvec
iter.
Setting exfat's splice_write to iter_file_splice_write fixes this and lets
fsx (which originally detected the problem) run to success from
the xfstests harness.

The timestamp for access_time has double seconds granularity(There is no
10msIncrement field for access_time unlike create/modify_time).
exfat's atimes are restricted to only 2s granularity so after
we set an atime, round it down to the nearest 2s and set the
sub-second component of the timestamp to 0.

granularity of timestamps, and for exfat that seems to be 10ms, so
set s_time_gran to 10000000ns. Without this, in-memory timestamps
change when they get re-read from disk.

Consider a case where ep0 is not in setup stage and composition
switch happens. Currently DWC3_DEPCMD_ENDTRANSFER command is not
issued on ep0 which means that the transfers are not flushed out
and driver clears the run/stop bit hence stopping the controller.
Now as soon as driver sets the run/stop bit controller tries to
access the trb from the previous session which is already unmapped
resulting in SMMU fault.
Fix this by unconditionally issuing DWC3_DEPCMD_ENDTRANSFER
command on ep0. Although it is not specified in the data book
but if we know for sure that we are anyway going to stop the
controller then we can issue ENDTRANSFER command on ep0.
