[PATCH v3 0/3] arm: demuxed ID registers (CCSIDR_EL1)

[Sebastian Ott <sebott@redhat.com>]

Handle the demuxed ID register CCSIDR_EL1 as part of the
idregs array. V2 of this series was posted here:
https://lore.kernel.org/qemu-devel/20260204133229.297061-1-cohuck@redhat.com/

Connie asked me to carry these forward.
Changes V2->V3:
* removed extra idregs_demux[] array based on suggestion from Richard
* removed COPY_IDREG_DEMUX suggested from Eric
* add CSSELR_MAX define
* rebased to current master
* removed my R-Bs

We still manually add the register definition to target/arm/cpu-sysregs.h.inc
- can we add special handling for that in the script that generates this?
