You mean this?

-#define ACCESS_INTR_MASK                       BIT(0)
-#define ACCESS_NO_IRQ_SUSPEND                  BIT(1)
-#define ARBITRATION_SEMAPHORE                  BIT(2)
-
-#define MODEL_MSCC_OCELOT                      BIT(8)
-#define MODEL_BAIKAL_BT1                       BIT(9)
-#define MODEL_AMD_NAVI_GPU                     BIT(10)
-#define MODEL_MASK                             GENMASK(11, 8)
+#define ACCESS_INTR_MASK                       0x00
+#define ACCESS_NO_IRQ_SUSPEND                  0x01
+#define ARBITRATION_SEMAPHORE                  0x02
+
+#define MODEL_MSCC_OCELOT                      0x08
+#define MODEL_BAIKAL_BT1                       0x09
+#define MODEL_AMD_NAVI_GPU                     0x0a
+#define MODEL_MASK                             0x78

I actually like more bitfield to plain numbers.
