drm/panthor: Pass an iomem pointer to GPU register access helpers

Convert the Panthor register access helpers to take an iomem pointer
instead of a panthor_device pointer.

This makes the helpers usable with block-local registers instead of
routing all accesses to go through ptdev->iomem. It is a preparatory
change for splitting the register space by components and for moving
callers away from cross-component register accesses.

No functional change intended.

v3:
- Pick up R-bs from Liviu and Steve
v2:
- Pick up Ack from Boris.
