The latest RHF/RISC-V goes boot loop like:

Starting on RV64 0x0 0xbfe00000
Starting on RV64 0xbfe00000 0x0
PANIC: panicked at src/fdt.rs:31:27:
Failed to create device tree object: BadPtr

I found that the issue first appears after commit af0d3c7, which updates Rust toolchain to nightly-2023-08-11 from nightly-2023-05-26. I also found that the issue appears from nightly-2023-06-07 by bisecting the Rust nightly toolchain.

riscv64: Avoid F and V instruction generation
e20922a 
As reported in issue cloud-hypervisor#299, the latest RHF goes boot loop since
`nightly-2023-06-07` Rust toolchain. This is because the recent Rust
generates code that includes F and V extensions, which we need to enable
these features on startup. This commit disables generation of these
extensions as a workaround.
