target/arm: Remove target_ulong use in hvf_handle_psci_call()

Similarly to commit 3580aa03547 ("target/arm/tcg/psci.c: make compilation unit common") which replaced the target_ulong use in arm_handle_psci_call(), replace the one in hvf_handle_psci_call. This could be vaddr, because entry is the start pc for the on-lining cpu, but we prefer uint64_t because this is what we get in param[] and pass to arm_set_cpu_on().
