ALSA<-OSS emulation
Got rid of the unused float codes (the legacy code for sharing with ALSA
library).
Add assert to the invalid conversion indices which results in oops
(just to be sure).

AC97 Codec Core,Intel8x0 driver,VIA82xx driver
Since there are many ac97_quirk values, the number is no longer good to
remember what it really means.  Now ac97_quirk option becomes as a string
option, and more undstandable.  For example, you can pass like
'ac97_quirk=hp_only'.  The old number is still kept and parsed for backward
compatibility.

Signed-off-by: Takashi Iwai <tiwai@suse.de>

PCM Midlevel
Fix suggested by Benjamin Herrenschmidt <benh@kernel.crashing.org>

On architectures like PPC, char is handled as 'unsigned char', thus the
pcm_format_data table entries with -1 give a positive 255.  This causes
Oops with OSS-emulation on such architectures.

The patch simply adds the right signed/unsigned prefix to fix this problem.
