> The "ethtool -d" handler reads registers in the ice_regs_dump_list array and
> returns read values back to the userspace.
> 
> The register offsets PFINT0_ITR* are not valid as per the specification and
> reading these causes a "unable to handle kernel paging request" bug in the
> driver. Remove these registers from ice_regs_dump_list.
