intel-hda: fix codec addressing.
The HDA bus supports up to 15 codecs, with addresses 0 ... 14.
We get that wrong in two places:
* When handing out addresses we accept address 15 as valid.
* The bitmasks for two registers (WAKEEN and STATESTS) don't
have bit 14 set.
This patch fixes it.
[ v2: codestyle: add braces ]
