[coreboot] SB600 HDA can't find codec fix

[Dan Lykowski]

Diff was being silly and I wanted to get the patch posted before I left work for the day. I've cleaned up the patch and included it.

I wasn't able to find where INTA was used so I used what the RPR lists as default. INTG. After looking at the mptable, I agree INTA is the correct answer. I've corrected it. I used dev_find_slot because I copied from the SATA driver. I've added the comment just like the SATA driver has. I don't know what the difference is, or why the SATA driver did this.

The reordering was based on what order things happen in the BIOS Developers guide, RPR, and SATA driver. I fixed the order of the devices that didn't matter to clean up the change log.
1. Enable the Chip
2. Setup the SMBus registers
3. Setup the Device Registers
4. Look for Codec
5. Init Codec

The codec init was changed to match the description in the RRG pg 235.
Mem Reg: Base + 08h Bit 0. There were unneeded things happening.

So here is the second try.

Thanks,
Dan Lykowski
