device/azalia_device: Add mainboard hook to program codecs
On some mainboards, codec configuration depends on settings that are
only known at runtime, which is impossible to specify using one verb
table. Add an optional `mainboard_azalia_program_runtime_verbs` hook
where mainboards can program runtime-dependent codec verbs.
