[PATCH 06/23] drm/amd/display: fix warning in amdgpu_dm_crtc_configure_crc_source()

[jdhillon]

From: Hamza Mahfooz <hamza.mahfooz at amd.com>

If we build the kernel without CONFIG_DRM_AMD_SECURE_DISPLAY set, we get
the following compile warning:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_crc.c: In function ‘amdgpu_dm_crtc_configure_crc_source’:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_crc.c:204:13: warning: unused variable ‘i’ [-Wunused-variable]
  204 |         int i, ret = 0;
      |             ^

So, guard variable i around CONFIG_DRM_AMD_SECURE_DISPLAY.

Fixes: 98f02f4c7050 ("SWDEV-351660 - dc: Implement multiple secure display")
