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.
