Subject: pata_via: fix VT6410/6415/6330 detection issue

From: JosephChan@via.com.tw <JosephChan@via.com.tw>

commit bc8a67386fd462914269fa93446e1891955a8bb3 upstream.

When using VT6410/6415/6330 chips on some VIA's platforms, the HDD
connection to VT6410/6415/6330 cannot be detected.

It is because the driver detects wrong via_isa_bridge ID, and then
causes this issue to happen.
