[PATCH] docs/system: add FEAT_AA32 and FEAT_AA64 to emulation list

Posted by Alex Bennée 3 hours ago

This is just a documentation tweak as we already support both.
FEAT_AA32 implies FEAT_AA32EL0. FEAT_AA64 implies FEAT_AA64EL[0123].

This is however useful if you are using emulation.rst as a source of
truth of what QEMU emulates and when cross checking with
Features.json from Arm.
