rk27xx: Fix commit_discard_idcache()

This version resembles how OF handle cache invalidates.
This seems to fix mysterious data aborts on plugin/codec loading
after introducing frequency scaling.

Credit goes to mortalis for pinpointing the reason of aborts.

Initial opus codec support
Synchronised with opus repo on github (https://github.com/freqmod/rockbox-opus)

Status:
* Seeking ported from speex, but fails on some cases (e.g. seek to granule 0)
* ReplayGain parsing needs to be reworked, we do vorbis-style replaygain now.
  http://wiki.xiph.org/OggOpus#Comment_Header explicitly forbids these in
  favour of R128_TRACK_GAIN tag.
* No optimisation yet, source files still nearly identical to opus upstream
* Multi-stream opus files may not be parsed correctly

checkwps: Do not error out on rwps for non-remote targets.

This breaks themes on the theme site (that ship an rwps for remote targets) for
non-remote targets. As rockbox just ignores the rwps checkwps now does the same.

Fix type cast for LCD_BUFF.

We should cast to (volatile uint32_t*) here, because attempt to refer to volatile
object through use of an lvalue with non-volatile-qualified type will result in
undefined behavior.
