ALSA: ctxfi: fix comment syntax in file headers

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
There are files in sound/pci/ctxfi which follow this syntax in their file
headers, i.e. start with '/**' like comments, which causes unexpected
warnings from kernel-doc.

E.g., running scripts/kernel-doc -none on sound/pci/ctxfi/ctresource.c
causes this warning:
"warning: wrong kernel-doc identifier on line:
* Copyright (C) 2008, Creative Technology Ltd. All Rights Reserved."

Similarly for other files too.

Provide a simple fix by replacing the kernel-doc like comment syntax with
general format, i.e. "/*", to prevent kernel-doc from parsing it.

ALSA: ctxfi: changed void * to struct hw *

in the code we have void *hw and while using we are always typecasting
it to (struct hw *). it is better to use void type of pointer when we
store different types of pointer , but in this code we are only having
struct hw.
So changed all the relevant reference of void *hw to struct hw *hw,
without any modification of the existing code logic.
the next patch of the series will remove the typecasting which is
not required now.

ALSA: pci: remove __dev* attributes

CONFIG_HOTPLUG is going away as an option. As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

ALSA: ctxfi: Add support for Creative Titanium HD

Initialise model-specific DAC and ADC parts.
Add controls for output and mic source selection.
Rename some mixer controls according to ControlNames.txt.
Remove Playback switches for Line-in and IEC958-in - these
were controlling the input mute/unmute which affected
capture too. Use the capture switches to control the
input mute/unmute instead - it's less confusing.
Initialise the WM8775 to invert the left-right clock
to swap the left and right channels of the mic and aux
input.

ALSA: ctxfi - Use native timer interrupt on emu20k1

emu20k1 has a native timer interrupt based on the audio clock, which
is more accurate than the system timer (from the synchronization POV).
This patch adds the code to handle this with multiple streams.

The system timer is still used on emu20k2, and can be used also for
emu20k1 easily by changing USE_SYSTEM_TIMER to 1 in cttimer.c.
