scsi: ufs: host: mediatek: Fix adapt issue after PA_Init
Address the issue where the host does not send adapt to the device after
PA_Init success. Ensure the adapt process is correctly initiated for
devices with IP version MT6899 and above, resolving communication issues
between the host and device.
