hw/mips: Include missing 'cpu.h' header
"target/mips/cpu.h" is indirectly pulled in via the "system/kvm.h" header, which next commit will remove. Explicitly include the "cpu.h" header, otherwise we'd get: hw/mips/mips_int.c:29:5: error: use of undeclared identifier 'MIPSCPU' 29 | MIPSCPU *cpu = opaque; | ^ hw/mips/mips_int.c:30:5: error: use of undeclared identifier 'CPUMIPSState' 30 | CPUMIPSState *env = &cpu->env; | ^ hw/mips/loongson3_virt.c:156:39: error: unknown type name 'MIPSCPU' 156 | static uint64_t get_cpu_freq_hz(const MIPSCPU *cpu) | ^ Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20260511135312.38705-4-philmd@linaro.org>
