[PULL 10/23] target/ppc: Improve KVM hypercall trace

[Daniel Henrique Barboza]

From: Fabiano Rosas <farosas@linux.ibm.com>

Before:

  kvm_handle_papr_hcall handle PAPR hypercall
  kvm_handle_papr_hcall handle PAPR hypercall
  kvm_handle_papr_hcall handle PAPR hypercall
  kvm_handle_papr_hcall handle PAPR hypercall
  kvm_handle_papr_hcall handle PAPR hypercall
  kvm_handle_papr_hcall handle PAPR hypercall

After:

  kvm_handle_papr_hcall 0x3a8
  kvm_handle_papr_hcall 0x3ac
  kvm_handle_papr_hcall 0x108
  kvm_handle_papr_hcall 0x104
  kvm_handle_papr_hcall 0x104
  kvm_handle_papr_hcall 0x108
