Some ASIMD FP convert instructions have incorrect scheduling
information. These instructions currently have latency 2, throughput 4
and utilise pipeline V. This patch corrects the scheduling models to
match the relevant Software Optimization Guide.
The V1 and V2 Software Optimization Guide show that ASIMD FP convert
instructions should all utilise pipelines V02. Their execution latency
and throughput should also differ depending on form. See section 3.17
"ASIMD floating-point instructions" in the Neoverse-V1 and Neoverse-V2
Software Optimization Guide for characteristics of instruction
performance.
