drm/amd/display: Fix wrong format specifier in amdgpu_dm.c

commit 655c167edc8c260b6df08bdcfaca8afde0efbeb6 upstream.

[Why]
Currently, the 32bit kernel build fails due to an incorrect string
format specifier. ARRAY_SIZE() returns size_t type as it uses sizeof().
However, we specify it in a string as %ld. This causes a compiler error
and causes the 32bit build to fail.

[How]
Change the %ld to %zu as size_t (which sizeof() returns) is an unsigned
integer data type. We use 'z' to ensure it also works with 64bit build.
