Call __phys_mem_access_prot() from the fbdev mmap helper fb_pgprotect().
Allows us to avoid the file argument, which can then be removed from
fB_pgprotect() entirely. No other architecture uses the parameter.

Remove 'file' parameter from struct machdep_calls.phys_mem_access_prot
and its implementation in pci_phys_mem_access_prot(). The file is not
used on PowerPC. By removing it, a later patch can simplify fbdev's
mmap code, which uses phys_mem_access_prot() on PowerPC.

As qaic drivers base device is connected to host via PCI framework, it
makes sense to register in PCI framework at the beginning of module
init.

Usages of DRM_IVPU_BO_UNCACHED should be replaced by DRM_IVPU_BO_WC.
There is no functional benefit from DRM_IVPU_BO_UNCACHED if these
buffers are never mapped to host VM.
This allows to cut the buffer handling code in the kernel driver
by half.

Use struct drm_gem_shmem_object as a base for struct ivpu_bo.

A BO for a QAIC device has two states -
1. Allocated
2. Sliced
A BO can be allocated at any time, and is initialized in the allocated state.
A BO can transition to the sliced state via ATTACH_SLICE_BO. This prepares the
BO for use with an active workload. Currently a BO in the sliced state can

Once the BO is declared 'sliced' by setting bo->sliced to true we can
