If a hardware is not detected there is a kernel crash
due to not initialized snd_miro->aci pointer. This pointer
is initialized after detection of the opti (miro) chip.

This bug was introduced by patches to expose
ACI mikser outside the snd-miro driver.

1. Set the third argument of the snd_device_new to not NULL, so there is
   no warning about bug during chip detection. The third argument is not
   used in this driver. It was changed in my previous patch.

2. Remove the fm_port and mpu_port fields from the snd_es18xx structure.
   They can be converted to function arguments.

3. Remove the dmaN_size fields from the snd_es18xx structure. These
   values are used only in pointer functions and can be easily calculated.

4. Remove the ctrl_lock spinlock which is used only in one read function
   which is called once during chip initialization. There are many
   writes to the same register and they are not protected on purpose
   (see the comment ina the snd_es18xx_config_write()).

5. Use the first part of the text5Sources string table as the text4Soruces
   table (they are the same).

6. Merge the same cases for the ES1887 and ES1888 when setting chip's caps.

7. Move the snd_es18xx_reset() to __devinit section.

The cs4236 was two step detection with call to the snd_wss_free()
between two steps. The snd_wss_free() did not free a sound device
created in the snd_wss_create(). This caused an OOPS during module
removal as the same sound device was released twice. The same OOPS
happened if the cs4236 module loading failed.

Fix this by adapting the snd_cs4236_create() to correctly work with
chips less capable then cs4236. The snd_cs4236_create() behaves the
same as the snd_wss_create() if the chip is less capable than the cs4236.

If spin_lock_irqsave is called twice in a row with the same second
argument, the interrupt state at the point of the second call overwrites
the value saved by the first call.  Indeed, the second call does not need
to save the interrupt state, so it is changed to a simple spin_lock.

The semantic match that finds this problem is as follows:

Adding MPU-401 support to cmi8330 driver could cause a regression (non-working
sound) on a system where there is no free IRQ for the MPU-401 device (which
is not very uncommon as this card requires two separate IRQs plus a third one
for MPU-401).

When MPU-401 PnP configuration fails (mostly because of unavailable IRQ), just
ignore MPU-401 and continue without it.

My CMI8329 had OPL3 port specified in SB16 resources. But now I found out that
it was my modification of the card's PnP EEPROM a couple of years ago (can be
done using C9SETROM.EXE utility). I did it because the OPL3 port was
completely missing from PnP data. It seems to be hardwired to 0x388 on
CMI8329.

Find OPL3 port automatically by searching in WSS and SB16 resources. If not
found, assume that it's hardwired to 0x388.

cs4232 and cs4236 driver merge to solve PnP BIOS detection.

Also, the patch adds recognition if the chip is cs4236b+
or earlier part. This unifies drivers for both cs4232
and cs4236+ chips. It allows to use the PnP BIOS
detection for the cs4236+ chips. Previously, only
the snd-cs4232 could be detected by the PnP BIOS.

The cs4232+ cards reports two separate PnP BIOS ids.

The patch adds search for the second id to find out
resources assigned to a control port.
