Subject: [PATCH] drm/amd/amdgpu: make undeclared variables static

Make the `amdgpu_lockup_timeout` and `amdgpu_exp_hw_support` variables
static to remove the following sparse warnings:
drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c:103:19: warning: symbol 'amdgpu_lockup_timeout' was not declared. Should it be static?
drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c:117:18: warning: symbol 'amdgpu_exp_hw_support' was not declared. Should it be static?
