Subject: [PATCH 2/4] fix: uuid: Decouple guid_t and uuid_le types and
 respective macros (v6.3)

See upstream commit :

  commit 5e6a51787fef20b849682d8c49ec9c2beed5c373
  Author: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
  Date:   Tue Jan 24 15:38:38 2023 +0200

    uuid: Decouple guid_t and uuid_le types and respective macros

    The guid_t type and respective macros are being used internally only.
    The uuid_le has its user outside the kernel. Decouple these types and
    macros, and make guid_t completely internal type to the kernel.

Upstream-Status: Backport
