[PATCH for-9.0 2/5] target/riscv/kvm: change KVM_REG_RISCV_FP_D to u64

[Daniel Henrique Barboza]

KVM_REG_RISCV_FP_D regs are always u64 size. Using kvm_riscv_reg_id() in
RISCV_FP_D_REG() ends up encoding the wrong size if we're running with
TARGET_RISCV32.

Create a new helper that returns a KVM ID with u64 size and use it with
RISCV_FP_D_REG().
