The RISC-V QEMU port currently has lot of preprocessor directives that
check if we are targetting a 32-bit or 64-bit CPU. This means that the
64-bit RISC-V target can not run 32-bit CPUs. This is different to most
other QEMU architectures and doesn't allow us to mix xlens (such as when
running Hypervisors with different xlen guests).
This series is a step toward removing some of those to allow us to use
32-bit CPUs on 64-bit RISC-V targets.
v3:
- Address Richard's comments
v2:
- Rebase on the latest RISC-V tree

hw/riscv: spike: Remove compile time XLEN checks
hw/riscv: sifive_u: Remove compile time XLEN checks
target/riscv: fpu_helper: Match function defs in HELPER macros
target/riscv: Add a riscv_cpu_is_32bit() helper function
target/riscv: Specify the XLEN for CPUs
target/riscv: cpu: Remove compile time XLEN checks
target/riscv: cpu_helper: Remove compile time XLEN checks
target/riscv: csr: Remove compile time XLEN checks
target/riscv: cpu: Set XLEN independently from target
