Subject: [PATCH 06/12] drm/amd/display: Remove unused variable 'mc_vm_apt_default'

Compiling AMD GPU drivers displays a warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_hubp.c: In function ‘hubp3_set_vm_system_aperture_settings’:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_hubp.c:50:30: warning: variable ‘mc_vm_apt_default’ set but not used [-Wunused-but-set-variable]

Get rid of it by removing the variable.
