Merge: cpufreq: use acpi_cpufreq on x86 processors instead of cppc_cpufreq

MR: https://gitlab.com/redhat/rhel/src/kernel/rhel-9/-/merge_requests/4462

JIRA: https://issues.redhat.com/browse/RHEL-112816

Resolves: 112816

AMD processors are experiencing slow performance on -604 and later kernels because a configuration change caused acpi_cppc_cpufreq to be compiled on x86 builds. acpi_cppc_cpufreq was being used preferentially over acpi_cpufreq. acpi_cppc_cpufreq does not support boost, so the faster boost P-states were not available.

Adjust the configuration files so that acpi_cppc_cpufreq isn't build on x86 builds, which matches upstream behavior.
