This adds the latest Samsung exfat driver to fs/exfat. This is an
implementation of the Microsoft exFAT specification. Previous versions
of this shipped with millions of Android phones, and a random previous
snaphot has been merged in drivers/staging/.

Compared to the sdfat driver shipped on the phones the following changes
have been made:

 - the support for vfat has been removed as that is already supported
   by fs/fat
 - driver has been renamed to exfat
 - the code has been refactored and clean up to fully integrate into
   the upstream Linux version and follow the Linux coding style
 - metadata operations like create, lookup and readdir have been further
   optimized
 - various major and minor bugs have been fixed

We plan to treat this version as the future upstream for the code base
once merged, and all new features and bug fixes will go upstream first.

v5:
 - Remove a blank line between the message and the error code in
   exfat_load_upcase_table.
 - Move brelse to the end of the while loop and rename label with
   free_table in exfat_load_upcase_table.
 - Move an error code assignment after a failed function call.
 - Rename labels and directly return instead of goto.
 - Improve the exception handling in exfat_get_dentry_set().
 - Remove ->d_time leftover.
 - fix boolreturn.cocci warnings.

v4:
 - Declare ALLOC_FAT_CHAIN and ALLOC_NO_FAT_CHAIN macros.
 - Rename labels with proper name.
 - Remove blank lines.
 - Remove pointer check for bh.
 - Move ep into loop in exfat_load_bitmap().
 - Replace READ/WRITE_ONCE() with test_and_clear_bit() and set_bit().
 - Change exfat_allow_set_time return type with bool.

v3:
 - fix wrong sbi->s_dirt set.

v2:
 - Check the bitmap count up to the total clusters.
 - Rename goto labels in several places.
 - Change time mode type with enumeration.
 - Directly return error instead of goto at first error check.
 - Combine seq_printf calls into a single one.
