scsi: ufs: host: mediatek: Add DDR_EN setting
On MT6989 and later platforms, control of DDR_EN has been switched from
SPM to EMI. To prevent abnormal access to DRAM, it is necessary to wait
for 'ddren_ack' or assert 'ddren_urgent' after sending 'ddren_req'.
Introduce the DDR_EN configuration in the UFS initialization flow,
utilizing the assertion of 'ddren_urgent' to maintain performance.
