0b94a70702 nvscic2c-pcie: update endpoint function deinit
In Thor core_deinit event is issue from pcie_epc_stop(),
Which mean we can not call pci_epc_unmap_addr() in core_deinit
due to mutex deadlock.
Release epc->lock in core_deinit before calling epc-core API's.
Take back mutex before returning.

d1f2b6a051 nvscic2c: Add Thor support
Configure BAR and MSI for Thor.

Add checks for chip id for chip specific code
between Orin and Thor.

Separate Stream ID's are assigned to upstream and downstream
struct device in Rootport client driver.
While accessing Rootport local memory upstream Stream ID should be used.
While accessing memories over BAR downstream Stream ID should be used.

b0ff4f1358 pci: endpoint: Update drivers for Linux v6.11
For Linux v6.11, the 'pci_epc_event_ops' structure 'core_init' callback
was renamed to 'epc_init' and a new 'epc_deinit' callback was added.

Update the PCI endpoint drivers for Linux v6.11 by:

 1. Adding tests to conftest to detect the presence of 'epc_init' and
    'epc_deinit'.
 2. Update the drivers as necessary to use the appropriate callback
    depending upon what is present in the kernel.

- Import DMA_BUF "MODULE_IMPORT_NS(DMA_BUF);" to avoid below error
"ERROR: modpost: module nvscic2c-pcie-epc uses symbol dma_buf_* from

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.
