pc: q35: Bump max_cpus to 1024
Since KVM_MAX_VCPUS is currently defined to 1024 for x86 as shown in
arch/x86/include/asm/kvm_host.h, update QEMU limits to the same number.
In case KVM could not support the specified number of vcpus, QEMU would
return the following error message:
qemu-system-x86_64: kvm_init_vcpu: kvm_get_vcpu failed (xxx): Invalid argument
Also, keep max_cpus at 288 for machine version 8.0 and older.
