drm/amd/display: Replace inline NUM_ELEMENTS macro with ARRAY_SIZE

Browse Source 
Replaces the use of local NUM_ELEMENTS macro with the ARRAY_SIZE macro
defined in <linux/array_size.h>.

This aligns with existing coccinelle script array_size.cocci which has
been applied to other sources in order to remove inline
sizeof(a)/sizeof(a[0]) patterns from other source files.
