From: Andrew Jones <ajones@ventanamicro.com>

The hypervisor should decide what it wants to enable. Zero all
configuration enable bits on reset.

Also, commit ed67d63798f2 ("target/riscv: Update CSR bits name for
svadu extension") missed one reference to 'hade'. Change it now.

Fixes: 0af3f115e68e ("target/riscv: Add *envcfg.HADE related check in address translation")
Fixes: ed67d63798f2 ("target/riscv: Update CSR bits name for svadu extension")
