Arnd Bergmann 6437a549ae drm/panfrost: fix GENERIC_ATOMIC64 dependency 
On ARMv5 and earlier, a randconfig build can still run into

WARNING: unmet direct dependencies detected for IOMMU_IO_PGTABLE_LPAE
  Depends on [n]: IOMMU_SUPPORT [=y] && (ARM [=y] || ARM64 || COMPILE_TEST [=y]) && !GENERIC_ATOMIC64 [=y]
  Selected by [y]:
  - DRM_PANFROST [=y] && HAS_IOMEM [=y] && DRM [=y] && (ARM [=y] || ARM64 || COMPILE_TEST [=y] && !GENERIC_ATOMIC64 [=y]) && MMU [=y]

Rework the dependencies to always require a working cmpxchg64.
