Marcin added the correct patch to the issue 3 weeks ago, so I'm giving
him authorship here. I only updated the comment a bit.
I am not fully sure is it everything needed to be honest.
Value 0x0000 in [3:0] means "The SVE instructions are implemented".
The way why it works is probably because QEMU keeps "there is no SVE" information
separately and do not emulate them.
ID_AA64PFR0_EL1.SVE is the primary indicator for SVE.
