The mentioned bits 14:8 are wrong as the functions always write
bits 15:8. What happens is visible in the written code. There is no need
for an extra comment.

Provide a library function to set the CPU frequency to minimum
value. This will result in the lowest possible CPU clock with
the lowest possible power consumption. This can be useful in mobile
devices where the power dissipation is limited.
This setting can be overruled by the OS if it has an p-state driver
which can adjust the clock to it's need.

by mp_run_on_all_cpus to run it on all cores.

The EFER and PAT MSRs are x86 architecturally defined. Therefore,
move the macro defintions to msr.h. Add 'paging' prefix to the
PAT and NXE pae/paging functions to namespace things a little better.

This patch adds few helper functions in CPU common libraray code
which are mainly needed for ACPI module. The functions those are
moved to cpu common code is removed from common acpi files.
TEST= System boots properly and no regression observed.
