Drop HDA support from 1.1.4

[Brendan Oakley]

To my knowledge, there has been little to no success with any HDA hardware with any 1.1.4 build. It is not going to be made to work properly in this development path. The experimental 1.9.x builds from Paul, by the accounts I have read, generally work better, so it seems that branch fills the void left if we just take it out of 1.1.4. It is better, then, to have the driver refuse to work with HDA than to have it load and crash, freeze, stutter, and otherwise behave poorly. Particularly in a "stable" release.

I have done a build with HDA removed, and am awaiting testing just to be sure that the last line of Intel AC'97 hardware that works in 1.1.4 still does. In theory it should not make any difference, but we want to be sure.

Additionally, because 1.1.4 and ReSync share drv32 in common, this change affects ReSync, and I'm not completely decided how I want to handle it there, so let me think about that before I commit this.

Test results came back fine. Even the Intel ICH6 AC'97 chips are unaffected if we remove the HDA code.

Committed in changeset:373.

Resync branch will retain the code, and it will still be compiled, but not linked in, for now.
