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.
