Understood. (The reason is BIT() used more than BIT_MASK() in kernel and 
also still I think better to use the macro instead of the shift operator 
as below.) Thank you.
   #define BIT(nr)                     (UL(1) << (nr))
...
-       NVME_CMBSZ_SQS          = 1 << 0,
-       NVME_CMBSZ_CQS          = 1 << 1,
-       NVME_CMBSZ_LISTS        = 1 << 2,
-       NVME_CMBSZ_RDS          = 1 << 3,
-       NVME_CMBSZ_WDS          = 1 << 4,
+       NVME_CMBSZ_SQS          = BIT(0),
+       NVME_CMBSZ_CQS          = BIT(1),
+       NVME_CMBSZ_LISTS        = BIT(2),
+       NVME_CMBSZ_RDS          = BIT(3),
+       NVME_CMBSZ_WDS          = BIT(4),
