Retire snd_sbc ISA sound card driver

Browse Source 
Along with the snd_sb8 and snd_sb16 drivers.  They supported ISA
Creative Sound Blaster and compatible sound cards.

Note that isa/sb.h is not removed, as it is still used by some PCI
sound card drivers.

ISA sound card drivers are deprecated as discussed on the current[1] and
stable[2] mailing lists.  Deprecation notices were added in e39ec8933b
and MFCd to stable branches.

Driver removals are being committed individually so that specific
drivers can be restored if necessary (either in FreeBSD or by downstream
projects).

.Nm snd_sb16 ,
.Nm snd_sb8
.Nd Creative Sound Blaster ISA and compatible bridge device driver
.Sh DEPRECATION NOTICE
This driver is scheduled for removal prior to the release of
.Fx 14.0 .
.Sh SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device sound"
.Cd "device snd_sbc"
.Cd "device snd_sb16"
.Cd "device snd_sb8"
.Ed
.Pp
Alternatively, to load the driver as a module at boot time, place the
following lines in
.Xr loader.conf 5 :
.Bd -literal -offset indent
snd_sbc_load="YES"
snd_sb16_load="YES"
snd_sb8_load="YES"
.Ed
.Pp
Non-PnP cards require the following lines in
.Xr device.hints 5 :
.Bd -literal -offset indent
hint.sbc.0.at="isa"
hint.sbc.0.port="0x220"
hint.sbc.0.irq="5"
hint.sbc.0.drq="1"
hint.sbc.0.flags="0x15"
.Ed
.Sh DESCRIPTION
The
.Nm
bridge driver allows the generic audio driver
.Xr sound 4
to attach to Creative Sound Blaster ISA (mostly SB16 or SB8, known as
SoundBlaster Pro) compatible audio cards.
.Pp
The value of flags specifies the secondary DMA channel.
If the secondary
DMA channel is C, set the flags to (C | 0x10).
For a sound card without the
secondary DMA channel, the flags should be set to zero.
.Sh HARDWARE
The
.Nm
driver supports the following sound cards:

.It sb_dspwr(XX) timed out.
A command to the DSP has timed out.
Check the I/O port configuration.
.It bad irq XX (5/7/9/10 valid)
The IRQ given to the driver is not valid.
