[CPUFREQ] Longhaul - Disable arbiter CLE266

Browse source

Please ignore previous message.

This patch is adding support for CPU connected to CLE266
chipset. For older CPU this is only way. For "Powersaver"
processor this way will be used if ACPI C3 isn't supported.

I have tested it. It seems to work exacly like ACPI.
But it is less safe. On CLE266 chipset port 0x22 is
blocking processor access to PCI bus too.
