[RFC PATCH v3 4/9] hw/arm/virt: Initialize the present cpu members

[Yanan Wang <wangyanan55@huawei.com>]

We create and initialize a cpuobj for each present cpu in
machvirt_init(). Now we also initialize the cpu member of
structure CPUArchId for each present cpu in the function.

This will be used to determine whether a cpu is present
when generating ACPI tables in later patches.
