On Intel 6-series PCHs, the GCAP register is R/WO (Read / Write Once), and needs to be written to after the HD Audio controller is taken out of reset. Add a Kconfig option to read and write back GCAP in order to lock it down. Follow-up commits will select this option when switching platforms to use common Azalia code, to preserve original behaviour.
