For SOC24 ASICs (RDNA4 / Navi 4x dGPUs) re-enabling PM features fails if an
S3 suspend got aborted, the same issue already handled for SOC21 and SOC15:

  commit df3c7dc5c58b ("drm/amdgpu: Reset dGPU if suspend got aborted")
  commit 38e8ca3e4b6d ("amdgpu/soc15: enable asic reset for dGPU in case of suspend abort")

The aborted resume fails with:

  amdgpu: SMU: No response msg_reg: 6 resp_reg: 0
  amdgpu: Failed to enable requested dpm features!
  amdgpu: resume of IP block <smu> failed -62

Apply the same workaround for soc24: detect the aborted-suspend state at
resume via the sign-of-life register and reset the device before re-init.

This is a workaround till a proper solution is finalized.

The read_indexed_register helper is duplicated across multiple files
with identical logic.

Move it to amdgpu_reg_access.c as
amdgpu_read_indexed_register and update all users accordingly.

No functional changes intended.
