Alistair Francis c5eb8d6336 target/riscv: rvzicbo: Fixup CBO extension register calculation
When running the instruction

```
    cbo.flush 0(x0)
```

QEMU would segfault.

The issue was in cpu_gpr[a->rs1] as QEMU does not have cpu_gpr[0]
allocated.

In order to fix this let's use the existing get_address()
helper. This also has the benefit of performing pointer mask
calculations on the address specified in rs1.

The pointer masking specificiation specifically states:

"""
Cache Management Operations: All instructions in Zicbom, Zicbop and Zicboz
"""

So this is the correct behaviour and we previously have been incorrectly
not masking the address.
