accel/ivpu: Remove support for uncached buffers
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. Usage of DRM_IVPU_BO_UNCACHED buffers was removed from user-space driver and will not be part of first UMD release.
