[PATCH] drm/amdgpu: fix printk format for size_t variable

[trix]

From: Tom Rix <trix@xxxxxxxxxx>

On mips64 allyesconfig, there is this build break
amdgpu_discovery.c:671:35: error: format '%ld' expects
  argument of type 'long int', but argument 4 has
  type 'size_t' {aka 'unsigned int'}
  DRM_DEBUG("match:%d @ ip_offset:%ld", ii, ip_offset);

For size_t, use %zu.

Fixes: a6c40b178092 ("drm/amdgpu: Show IP discovery in sysfs")
