selftests/resctrl: Fix non-contiguous CBM for AMD
[ Upstream commit 48236960c06d32370bfa6f2cc408e786873262c8 ]
The non-contiguous CBM test fails on AMD with:
Starting L3_NONCONT_CAT test ...
Mounting resctrl to "/sys/fs/resctrl"
CPUID output doesn't match 'sparse_masks' file content!
not ok 5 L3_NONCONT_CAT: test
AMD always supports non-contiguous CBM but does not report it via CPUID.
Fix the non-contiguous CBM test to use CPUID to discover non-contiguous
CBM support only on Intel.
