Aleksandr Mishin 2d3be509be drm: vc4: Fix possible null pointer dereference
[ Upstream commit c534b63bede6cb987c2946ed4d0b0013a52c5ba7 ]

In vc4_hdmi_audio_init() of_get_address() may return
NULL which is later dereferenced. Fix this bug by adding NULL check.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
