* Register programming error during device initialization
  especially for CT4730 / EV1938 chip, causing misconfigured mixer
  (David Xu), crippled after power cycle (Kevin Oberman). Fixed.
* Incorporate locking/spdif patches from Jon Noack / matk. Not all
  es137x can really do spdif, clean it up a bit to only let few capable
  chip. This adds a "hw.snd.pcm<unit>.spdif_enabled" sysctl until
  a more generic way of handling this from userland (by an ordinary
  user) is designed/implemented.
* Convert all bus_space_(read|write) to use es_rd/es_wr, simmilar
  with other drivers.
* Add tunable hw.snd.pcm<unit>.latency_timer sysctl to toggle pci
  latency timer value on the fly. Much noise / pop / crackling
  issues can be solved by increasing its value. Other people have
  pointed out to use pciconf instead, but this is just an added
  value specific for CT4730/EV1938.
* Remove es137x specific debug sysctl/code.
