PSD_GET_NUM_OF_PROCS keywords
This function must detect and return the number of usable x86 based processors that exist on the current platform. If the PSD detects that any of the processors are defective or non x86-based, it is the PSD's responsibility to setup the state of the PSD and hardware, such that all usable processors are logically ordered. For example, if there are 4 processors and CPU2 is defective, the CPU's should be ordered as follows: CPU0 = 0, CPU1 = 1, CPU2 (Defective), CPU3 = 2).
