target/i386: Update EPYC-Rome CPU model for Cache property, RAS, 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-Rome. The SVM
feature bits are used in nested guests.
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
