v4:
-Whitespace fixes
-Add MODULE_PARM_DESC for the module parameters
-Refactor qaic_open error handling
-Shorten mhi boot error message
-Remove extranious reset check
-Remove _ prefix in qaic_control structs
-Refactor encode_dma()
-Refactor __qaic_execute_bo_ioctl
-Remove extraniuous open_count checks
-List drm-misc tree in MAINTAINERS

v3:
-Various style updates and word smithing
-Remove unused function declarations
-Drop iommu workaround for sg lists and outdated reserve_pages()
-Remove unnecessary includes
-Refactor qaic_pci_probe()
-Use FIELD_PREP for ENCODE_SEM
-Gate qaic subdirectory on the kconfig symbol
-Add [e-mail] to MAINTAINERS entry
-Rename copy_sgt()
-Correct guard macro for qaic.h and cplusplus macro
-Add comment in qaic_mhi_remove
-Fix qaic_open use after free
-Use devm allocs in qaic_mhi_register_controller()
-Remove partition device ioctl.

v2:
-Addressed comments from RFC
-Reduced the code to the core minimum by dropping telemetery, etc
-Conversion to accel subsystem
-Dropped versioning
-Add mhi_qaic_cntl component
-Restructure the documentation
-Pull in a few fixes from the downstream tree
