Patch Review
**Status: Good. Acked-by Boris Brezillon.**
Adds `void __iomem *iomem` to `struct panthor_fw`, set to `ptdev->iomem + MCU_CONTROL_BASE` (0x700):
```c
+ fw->iomem = ptdev->iomem + MCU_CONTROL_BASE;
```
Register defines are rebased relative to MCU_CONTROL_BASE:
```c
-#define MCU_CONTROL 0x700
-#define MCU_STATUS 0x704
+#define MCU_CONTROL 0x0
+#define MCU_STATUS 0x4
```
All firmware register accesses switch from `gpu_read(ptdev->iomem, MCU_XXX)` to `gpu_read(fw->iomem, MCU_XXX)`. The arithmetic is correct: `fw->iomem + 0x0` = `ptdev->iomem + 0x700`, matching the original `ptdev->iomem + 0x700`.
Clean and straightforward.
