ufs: Add missing memory barriers Add missing wmb() and mb() barriers in the u-boot UFS core framework driver to allow registers updates to happen before follow-up read operations. This makes the barrier placement similar to the Linux UFS driver, synced from the Linux v6.9 release. Starting from the v6.10 release, the barriers were replaced with a register read-back in [1], this will ported to u-boot in a second time.
