Intel-SIG: commit 74b2fc88 dmaengine: idxd: Use cpu_feature_enabled().
Incremental backporting patches for DSA/IAA on Intel Xeon platform.

--------------------------------

When testing x86 feature bits, use cpu_feature_enabled() so that
build-disabled features can remain off, regardless of what CPUID says.
