A patch series should be bisectable. Removing max_num_rtt from struct
ufs_hba_variant_ops before the code is removed from the MediaTek driver
that sets that variable introduces a build break. Please keep
'max_num_rtt' in this patch and add a third patch to this series that
removes 'max_num_rtt'.

Thanks,

Bart.
