Update sw usage flags handling
Inspired by Rob Herring suggestion and gbm_gralloc implementation
Add missing support for GRALLOC_USAGE_SW_READ_OFTEN,
GRALLOC_USAGE_SW_WRITE_OFTEN usage flags
mapping them to PIPE_BIND_LINEAR
Fixes the mouse cursor and message panes artifacts
happening with gralloc_drm_pipe, tested with amdgpudrmfb
No observed regression on swrast llvmpipe
