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

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.

+	  for systems using PulseAudio.  The default 64 is chosen just
