hw: intc: Use cpu_by_arch_id to fetch CPU state

Qemu_get_cpu uses the logical CPU id assigned during init to fetch the
CPU state. However APLIC, IMSIC and ACLINT contain registers and states
which are specific to physical hart Ids. The hart Ids in any given system
might be sparse and hence calls to qemu_get_cpu need to be replaced by
cpu_by_arch_id which performs lookup based on the sparse physical hart IDs.
