ASoC: amd: acp: add a null check for chip_pdev structure
[ Upstream commit 98d919dfee1cc402ca29d45da642852d7c9a2301 ]
When acp platform device creation is skipped, chip->chip_pdev value will
remain NULL. Add NULL check for chip->chip_pdev structure in
snd_acp_resume() function to avoid null pointer dereference.
