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.
