KVM: Move architecture capability Kconfigs to header defines
With s390 hosting multiple independent KVM implementations within the
same kernel build (native s390 KVM and arm64 on s390), global Kconfig
selections force both implementations to inherit options that only apply
to one of them.
Replace global Kconfig options which only apply to one KVM
implementation with architecture-specific opt-in defines in the
respective <asm/kvm_host.h>. Only remove Kconfig symbols that would be
different on both s390 KVM implementations
- __KVM_HAVE_INVALID_WAKEUPS (formerly HAVE_KVM_INVALID_WAKEUPS)
- __KVM_HAVE_MSI (formerly HAVE_KVM_MSI)
- __KVM_HAVE_NO_POLL (formerly HAVE_KVM_NO_POLL)
- __KVM_HAVE_READONLY_MEM (formerly HAVE_KVM_READONLY_MEM)
- __KVM_HAVE_VCPU_RUN_PID_CHANGE (formerly HAVE_KVM_VCPU_RUN_PID_CHANGE)
This allows each architecture and guest implementation to configure its
supported capabilities independently in its kvm_host header and eliminates
adding unnecessary fallback stubs across different KVM targets.
