azalia: Make `set_bits` function non-static
There's many copies of this function in the tree. Make the copy in
azalia_device.c non-static and rename it to `azalia_set_bits`, then
replace all other copies with it. Since azalia_device.c is only built
when AZALIA_PLUGIN_SUPPORT is selected, select it where necessary.
This has the side-effect of building hda_verb.c from the mainboard
directory. If this patch happens to break audio on a mainboard, it's
because its hda_verb.c was always wrong but wasn't being compiled.
