Subject: [PATCH v2 1/1] firmware: tee_bnxt: Use UUID API for exporting the UUID

There is export_uuid() function which exports uuid_t to the u8 array.
Use it instead of open coding variant.

This allows to hide the uuid_t internals.

v2: resent with Cc to Christoph since the original maintainers are
