[PATCH] drm/nouveau: Fix DEVICE_PRIVATE dependencies

[Yue Haibing <yuehaibing@huawei.com>]

From: YueHaibing <yuehaibing@huawei.com>

During randconfig builds, I occasionally run into an invalid configuration

WARNING: unmet direct dependencies detected for DEVICE_PRIVATE
  Depends on [n]: ARCH_HAS_HMM_DEVICE [=n] && ZONE_DEVICE [=n]
  Selected by [y]:
  - DRM_NOUVEAU_SVM [=y] && HAS_IOMEM [=y] && ARCH_HAS_HMM [=y] && DRM_NOUVEAU [=y] && STAGING [=y]

mm/memory.o: In function `do_swap_page':
memory.c:(.text+0x2754): undefined reference to `device_private_entry_fault'

commit 5da25090ab04 ("mm/hmm: kconfig split HMM address space mirroring from device memory")
split CONFIG_DEVICE_PRIVATE dependencies from
ARCH_HAS_HMM to ARCH_HAS_HMM_DEVICE and ZONE_DEVICE,
so enable DRM_NOUVEAU_SVM will trigger this warning,
cause building failed.
