x86/percpu: Enable named address spaces for GCC 9.1+

Browse Source 
Enable named address spaces also for GCC 9, GCC 10 and GCC 11
releases. These compilers all produce kernel images that boot
without problems.

GCC_VERSION cutoff is arbitrary. It is primary a risk-reduction
cutoff, older compilers will be tested and enabled in linux 6.10
release.
