[CPUFREQ][4/8] acpi-cpufreq: Mark speedstep-centrino ACPI as deprecated
Mark ACPI hooks in speedstep-centrino as deprecated. Change the order in which speedstep-centrino and acpi-cpufreq (when both are in kernel) will be added. First driver to be tried is now acpi-cpufreq, followed by speedstep-centrino. Add a note in feature-removal-schedule to mark this deprecation.

+ This is deprecated and this functionality is now merged into

Use primarily the information provided in the BIOS ACPI tables
to determine valid CPU frequency and voltage pairings. It is
required for the driver to work on non-Banias CPUs.
