drm/panthor: Store IRQ register base iomem pointer in panthor_irq

Browse source

Update common IRQ handling code to work from an IRQ-local iomem base
instead of referencing block-specific interrupt register offsets.

Store the interrupt base address iomem pointer in struct panthor_irq and
switch the shared IRQ helpers to use generic INT_* offsets from that
local base. This removes the need for each caller to expose absolute IRQ
register addresses while keeping the common IRQ flow unchanged.

No functional change intended.

v3:
- Clean up definition of pwr->irq.iomem.
v2:
- Change IRQ request function to accept an iomem pointer instead of
  computing it from an offset argument.
