qemu: Remove hard-coding of Qemu machine options for ppc64le

Browse Source 
Hard-coded Qemu machine options create challenges when running Kata
with latest Qemu (v5.0) or with latest processor version.
This patch makes it configurable by leveraging the existing machine_accelerators
option in configuration.toml.

This patch fixes #2657 for ppc64le
