Add new types for TLV dB scale specified with min/max values instead
of min/step since the resolution can't match always with the one
a device provides. For example, usb audio devices give 1/256 dB
resolution while ALSA TLV is based on 1/100 dB resolution.
The new min/max types have less problems because the possible
rounding error happens only at min/max.Signed-off-by: Takashi Iwai

Added the definition of TLV dB range compound. It contains one or
more dB-range or linear-volume TLV entries with min/max ranges.
Used for volume controls with non-linear curves.Signed-off-by: Takashi Iwai

Added the definition of linear volume TLV type.
Some DSP chips and codecs (e.g. AK codec) use linear volume control.Signed-off-by: Takashi Iwai

This patch implements a TLV mechanism to transfer an additional information
like dB scale to the user space. The types might be extended in future.
