Aurabindo Pillai 1f3b22e4eb drm/amd/display: fix null pointer deref when plugging in display 
[Why&How]
When system boots in headless mode, connecting a 4k display creates a
null pointer dereference due to hubp for a certain plane being null.
Add a condition to check for null hubp before dereferencing it.
