标题	0000511: Don't initialize IDXD driver if MOVDIR64B or ENQCMDS is build-disabled
描述	IDXD driver uses boot_cpu_has() to test MOVDIR64B and ENQCMDS bits through CPUID for DSA or IAX device initialization. When any of these two bits are disabled in kernel (e.g., features in arch/x86/include/asm/disabled-features.h), cpu_feature_enabled() should be used to keep the features off regardless of what CPUID reports, and thus the device will not be enumerated.
