So, increase SND_SOC_TPLG_NUM_TEXTS to 32 to support 32

What do you mean by "Topology supports maximum of 32 configs for a
path"? I checked in alsa-lib and the same value of 16 is used.
I don't get how a change at the kernel level is going to help if the
information generated by alsatplg uses a different structure.
I also don't get how you enable this change, the code in skl-topology
only accesses the .priv structure in the enum, but if you change the
size of the texts array then all your pointers are incorrect so you'd
handle garbage data.
