ALSA: oxygen: fix distorted output on AK4396-based cards
When changing the sample rate, the CMI8788's master clock output becomes
unstable for a short time. The AK4396 needs the master clock to do SPI
writes, so writing to an AK4396 control register directly after a sample
rate change will garble the value. In our case, this leads to the DACs
being misconfigured to I2S sample format, which results in a wrong
output level and horrible distortions on samples louder than -6 dB.
To fix this, we need to wait until the new master clock signal has
become stable before doing SPI writes.

sound: make OSS sound core optional
sound/sound_core.c implements soundcore.ko and contains two parts -
sound_class which is shared by both ALSA and OSS and device
redirection support for OSS. It's always compiled when any sound
support is enabled although it's necessary only when OSS (the actual
one or emulation) is enabled. This is slightly wasteful and as device
redirection always registers character device region for major 14, it
prevents alternative implementation.
This patch introduces a new config SOUND_OSS_CORE which is selected
iff OSS support is actually necessary and build the OSS core part
conditionally.
If OSS is disabled, soundcore merely contains sound_class but leaving
it that way seems to be the simplest approach as otherwise sound_class
should be in ALSA core file if OSS is disabled but should be in
soundcore if OSS is enabled. Also, there's also the user confusion
factor.

By now, ioaddr_t should only be used by the deprecated ioctl, as it does not
correctly reflect the maximum ioport range at least on some architectures.
The header file primarily used for (in-kernel) PCMCIA device drivers
also deserved a major cleanup. This header file also serves as the dumping
