defs/cocovtio.d: Add ModCo80 COLoad bit mask for Co80 VDIO submodule This is for the CRT9128-based Co80 driver, not for the 6845-based CoWP driver (WordPak I/II/RS). The Co80 driver name has at some point also been used for the WordPak RS driver, however co80.asm is for a different chip, the CRT9128, used (at least) in a PBJ prototype. We later got a cowprs.asm driver for the WorkPak RS. The module name is CoWP and it uses the ModCoWP bit mask. Since VTIO (level 1) has hardcoded module names for the submodules, matched to a COLoad bit mask value, these two modules must have different COLoad bit masks to allow both to exist on the same system.
