Modify the dsc helpers to get max/min compressed bpp to accept
`const struct intel_crtc_state *` pointers instead of
`struct intel_crtc_state *`.
These helpers are not supposed to modify `crtc_state`.
Accepting const pointers will allow these helpers to be called from
functions that have const pointer to crtc_state.
