drm: drop i386 verification
Linux doesn't run on i386, anymore. See:
commit d55c5a93db2d5fa95f233ab153f594365d95b777
Author: H. Peter Anvin <hpa@linux.intel.com>
Date: Wed Nov 28 11:50:24 2012 -0800
x86, 386 removal: Remove CONFIG_CMPXCHG
All 486+ CPUs support CMPXCHG, so remove the fallback 386 support
code.
Furthermore, as the commit-message states, all 486+ CPUs support the
CMPXCHG instruction and thus even legacy DRM can run fine.
Drop the now superfluous "x86 == 3" check.
