m68k: mac: Fix macintosh_config for Mac II

[ Upstream commit 52ae3f5da7e5adbe3d1319573b55dac470abb83c ]

When booted on my Mac II, the kernel prints this:

    Detected Macintosh model: 6
    Apple Macintosh Unknown

The catch-all entry ("Unknown") is mac_data_table[0] which is only needed
in the unlikely event that the bootinfo model ID can't be matched.
When model ID is 6, the search should begin and end at mac_data_table[1].
Fix the off-by-one error that causes this problem.
