d0e427c6e1 drivers: Use conftest for vm_flags
The conftest script has a test for checking if the vm_area struct has a
const vm_flags member. So enable this test and use the definition
generated in the appropriate drivers.

0e6d4c804f nvscic2c: Implement Read-After-Write ordering WAR
- Ordering between message/data and host1x syncpoints is not enforced
   strictly.
 - Out of the possible WARs, implement dummy PCIe Read between
   data/message write and notifications towards peer / remote post-fences.
 - WAR: (IPC/messaging mode)For any UMD produced data towards peer,
   before notification is triggered, issue a dummy PCIe read  via CPU.
 - WAR: (streaming mode)DMA flush-ranges(data), wait for DMA interrupt,
   when success issue dummy PCIe reads via CPU on remote post-fences
   + issue CPU PCIe writes on each remote post-fence. To achieve this,
   CPU map every imported sync object.

nvscic2c enables xfer between two SoC connected over PCIe.
nvscic2c already available with K5.10

Major changes in nvscic2c-pcie for K5.15:
 Integrate with upstream PCIe endpoint function changes.

 Allocate new IOVA domain to be used for
 empty IOVA allocation.
 This IOVA range would be used in iommu_map() to map
 physical backing with IOMMU domain attached in PCIe device.

 Migrate from nvhost to host1x and tegra-drm interfaces.
