[Bug 147065] AMD/ATI SB700 should support two IDE channels

[Shane Huang]

Public bug reported:

Binary package hint: linux-source

SB700 supports one physical IDE channel, but SB700 SATA controller
supports combined mode. When the SATA combined mode is enabled,
two SATA ports(port4 and port5) share one IDE channel from IDE
controller, and PATA will share the other IDE channel.

Our previous patch above adding SB700 IDE device ID only support one
IDE channel, which contains bug. The attached patch fix the bug.

I have sent the patch to the linux kernel IDE maintainer, and will
post the upstream commit here when I get it.

Thanks
