topology2: common: pcm_caps: Change the periods_max from 1024 to 256 

HDA host DMA has limitation on the number of BDL entries which translates
to number of periods, this limit is 256.

The Chrome ALSA compliance test is eagerly try to use as many periods as
it can which exceeds the BDL limit and the stream cannot be started.

Fixes: b3a6d1c570 ("topology2: common: pcm_caps: Increase periods_max from 16 to 1024")
