[PATCH RESEND v7 04/12] target/riscv: add PRIV_VERSION_LATEST

[Daniel Henrique Barboza <dbarboza@ventanamicro.com>]

All these generic CPUs are using the latest priv available, at this
moment PRIV_VERSION_1_12_0:

- riscv_any_cpu_init()
- rv32_base_cpu_init()
- rv64_base_cpu_init()
- rv128_base_cpu_init()

Create a new PRIV_VERSION_LATEST enum and use it in those cases. I'll
make it easier to update everything at once when a new priv version is
available.
