Fix HDR10 MaxCLL and MaxFALL documentation
MaxCLL and MaxFALL should be in units of 1 nit as
specified in CEA-861.3, Appendix A.
A uint16_t is not large enough to specify the full
range of possible MaxCLL/MaxFALL values in units of
0.0001 cd/m^2. So conclude that the documentation
was just a copy/paste error.
