[PATCH] target/riscv: fix priv enum

[Nikita Shubin]

From: Nikita Shubin <n.shubin@yadro.com>

Add PRIV_VERSION_UNKNOWN to enum, otherwise PRIV_VERSION_1_10_0 will
be overwritten to PRIV_VERSION_1_12_0 in riscv_cpu_realize.

Fixes: a46d410c5c ("target/riscv: Define simpler privileged spec version 
numbering")
