[PULL 16/23] hw/arm/virt-acpi-build: Include missing 'cpu.h' header

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

"cpu.h" is indirectly pulled in by another header. Include
it explicitly in order to avoid when changing default CPPFLAGS path:

  hw/arm/virt-acpi-build.c:903:34: error: call to undeclared function 'arm_feature';
    903 |         uint32_t pmu_interrupt = arm_feature(&armcpu->env, ARM_FEATURE_PMU) ?
