Instance of Timer Library only using CPU resources.
Timer Library that only uses CPU resources to provide calibrated delays
on IA-32, x64, and IPF.
Note: A driver of type DXE_RUNTIME_DRIVER and DXE_SMM_DRIVER can use this TimerLib
in their initialization without any issues. They only have to be careful in
the implementation of runtime services and SMI handlers.
Because CPU Local APIC and ITC could be programmed by OS, it cannot be
used by SMM drivers and runtime drivers, ACPI timer is recommended for SMM
drivers and runtime drivers.
Note that for IA-32 and x64, this library only supports xAPIC mode. If x2APIC
support is desired, the SecPeiDxeTimerLibUefiCpu library can be used.
