Hi Zhiwei!

Zabha adds support AMO operations for byte and half word. If zacas has been
implemented,
zabha also adds support amocas.b and amocas.h.
More details is on the specification here:
https://github.com/riscv/riscv-zabha
The implemenation of zabha follows the way of AMOs and zacas.
This patch set is based on these two patch set:
1. https://mail.gnu.org/archive/html/qemu-riscv/2024-05/msg00207.html
2. https://mail.gnu.org/archive/html/qemu-riscv/2024-05/msg00212.html
These 2 series doesn't seem to apply on top of each other, doesn't matter which
order I try. Applying zimop/zcmop first, then zama16b:

If the series are dependent on each other perhaps it's easier to send everything
in a single 11 patches series.
Thanks,
