accel/qaic: Add uapi and core driver file Add the QAIC driver uapi file and core driver file that binds to the PCIe device. The core driver file also creates the accel device and manages all the interconnections between the different parts of the driver. The driver can be built as a module. If so, it will be called "qaic.ko".

accel/qaic: Support for 0 resize slice execution in BO Add support to partially execute a slice which is resized to zero. Executing a zero size slice in a BO should mean that there is no DMA transfers involved but you should still configure doorbell and semaphores. For example consider a BO of size 18K and it is sliced into 3 6K slices and user calls partial execute ioctl with resize as 10K. slice 0 - size is 6k and offset is 0, so resize of 10K will not cut short this slice hence we send the entire slice for execution. slice 1 - size is 6k and offset is 6k, so resize of 10K will cut short this slice and only the first 4k should be DMA along with configuring doorbell and semaphores. slice 2 - size is 6k and offset is 12k, so resize of 10k will cut short this slice and no DMA transfer would be involved but we should would configure doorbell and semaphores. This change begs to change the behavior of 0 resize. Currently, 0 resize partial execute ioctl behaves exactly like execute ioctl i.e. no resize. After this patch all the slice in BO should behave exactly like slice 2 in above example. Refactor copy_partial_exec_reqs() to make it more readable and less complex.

accel/qaic: Add QAIC_DETACH_SLICE_BO IOCTL Once a BO is attached with slicing configuration that BO can only be used for that particular setting. With this new feature user can detach slicing configuration off an already sliced BO and attach new slicing configuration using QAIC_ATTACH_SLICE_BO. This will support BO recycling. detach_slice_bo() detaches slicing configuration from a BO. This new helper function can also be used in release_dbc() as we are doing the exact same thing.
