ALSA: hda: Move CONFIG_SND_HDA_PREALLOC_SIZE into sound/hda/common

Browse Source 
CONFIG_SND_HDA_PREALLOC_SIZE is used only by controller.c in
sound/hda/common, hence it depends on CONFIG_SND_HDA.

Move the definition to the right place inside SND_HDA if/endif block
in sound/hda/common/Kconfig.

The old behaviour (Y) is obsolete and will be removed. Consider
to not enable this option.
config SND_HDA_PREALLOC_SIZE
int "Pre-allocated buffer size for HD-audio driver"
range 0 32768
default 0 if SND_DMA_SGBUF
default 64 if !SND_DMA_SGBUF
help
Specifies the default pre-allocated buffer-size in kB for the
HD-audio driver. A larger buffer (e.g. 2048) is preferred
for systems using PulseAudio. The default 64 is chosen just
for compatibility reasons.
On x86 systems, the default is zero as S/G allocation works
and no preallocation is needed in most cases.
Note that the pre-allocation size can be changed dynamically
via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
