ASoC: Intel: avs: Improve topology parsing of dynamic strings

Current mechanism replaces "%d" present in some routes and widget names
with SSP number. However there are also configurations which make use of
TDM number, in which case expected behavior would be to have string in
form of SSP:TDM - see implementation of avs_i2s_platform_register() in
sound/soc/intel/avs/pcm.c.

Implement custom function, which parses string and make use of it when
parsing topology. While at it make sure that we generate dynamic names
only if there is no multiple SSPs or TDMs defined.
