Daniel Henrique Barboza cc2bf69a36 target/riscv: add zicbop extension flag 
QEMU already implements zicbom (Cache Block Management Operations) and
zicboz (Cache Block Zero Operations). Commit 59cb29d6a5 ("target/riscv:
add Zicbop cbo.prefetch{i, r, m} placeholder") added placeholders for
what would be the instructions for zicbop (Cache Block Prefetch
Operations), which are now no-ops.

The RVA22U64 profile mandates zicbop, which means that applications that
run with this profile might expect zicbop to be present in the riscv,isa
DT and might behave badly if it's absent.

Adding zicbop as an extension will make our future RVA22U64
implementation more in line with what userspace expects and, if/when
cache block prefetch operations became relevant to QEMU, we already have
the extension flag to turn then on/off as needed.
