[PATCH v5 06/46] bios_emulator: Drop VIDEO_IO_OFFSET

[Simon Glass]

This is always zero in the source tree, so drop it.

While we are here, add a comment to _X86EMU_env since the symbol is
actually defined twice, which can cause confusion when building.

Changes in v5:
- Drop unnecessary 'it' in commit message
