ASoC: soc-utils: Remove PAGE_SIZE compile-time constant assumption

In pursuit of the goal of supporting boot-time page size selection,
remove use of PAGE_SIZE from the dummy_dma_hardware struct definition,
since the value is not known at compile-time for this config.

Given the previous parameters were "essentially random", let's just
hardcode them as 4K and 4K*2 to sidestep the need to boot-time patch the
structure with the selected PAGE_SIZE.
