target/i386: Update EPYC-Genoa for Cache property, perfmon-v2, RAS and SVM feature bits
Found that some of the cache properties are not set correctly for EPYC models. l1d_cache.no_invd_sharing should not be true. l1i_cache.no_invd_sharing should not be true. L2.self_init should be true. L2.inclusive should be true. L3.inclusive should not be true. L3.no_invd_sharing should be true. Fix these cache properties. Also add the missing RAS and SVM features bits on AMD EPYC-Genoa model. The SVM feature bits are used in nested guests. perfmon-v2 : Allow guests to make use of the PerfMonV2 features. succor : Software uncorrectable error containment and recovery capability. overflow-recov : MCA overflow recovery support. lbrv : LBR virtualization tsc-scale : MSR based TSC rate control vmcb-clean : VMCB clean bits flushbyasid : Flush by ASID pause-filter : Pause intercept filter pfthreshold : PAUSE filter threshold v-vmsave-vmload: Virtualized VMLOAD and VMSAVE vgif : Virtualized GIF fs-gs-base-ns : WRMSR to {FS,GS,KERNEL_GS}_BASE is non-serializing The feature details are available in APM listed below [1].
