Revert "module_adapter: dp: Decrease default heap size from 20k to 16k"

This reverts commit a32d983. It looks like this causes more trouble than it solves. 16k is not enough heap for 11025Hz to 48000Hz conversion. The inability to have two SRCs active at the same time is not as critical issue as failing some conversions completely. Signed-off-by: Jyri Sarha <jyri.sarha@linux.intel.com>
