Explicitely disable X2APIC support on legacy targets since the targeted
processor types do not support it anyway there.
Fixes FS#285.

commit 961c0eacea ('x86: fix lifting kernel CPU requirements and always
enable PAE') broke some older geode boards such as Soekris net4826.
Hence disable PAE on x86/legacy again in order to still support those
very old non-PAE capable CPUs.
Fixes FS#773 - PAE broke Soekris net4826

commit 89878f60f4 x86: lift kernel minimum CPU requirement to Pentium MMX
caused kconfig havoc. Fix this and make sure PAE is enabled even on legacy
CPUs as the minimum required CPU has been Pentium MMX for a while now and
hence PAE is supported even on the x86_legacy target.

CPU frequency scaling enables the operating system to scale the CPU
frequency up or down in order to save power. CPU frequencies can be
scaled automatically depending on the system load, in response to ACPI
events, or manually by userspace programs.
