[Qemu-ppc] [PATCH 03/14] target-ppc: Use float64 arg in helper_compute_fprf()

[Nikunj A Dadhania]

From: Bharata B Rao <address@hidden>

Use float64 argument instead of unit64_t in helper_compute_fprf()
This allows code in helper_compute_fprf() to be reused later to
work with float128 argument too.
