[PATCH] ASoC: soc-core: Increase the channel map size

[Ravulapati Vishnuvardhan Rao]

As per the need for new OEMs it is needed to increase the
number of channels size as some of the OEM have ten mics
and one speaker.
So for this it is important to make sure that channel map
needs to be increased.

The ASoC core currently provides default channel connection maps for up to
8 channels. Newer OEM designs can exceed this (for example, topologies with
10 microphones plus speaker paths), which makes the default maps too small.

Increase MAX_DEFAULT_CH_MAP_SIZE from 8 to 12 and extend the default
sync/1cpu/1codec mapping tables accordingly.

This keeps existing behaviour unchanged for <=8 channels while allowing
larger channel maps to be represented by default.
