Parameters
This A pointer to the EFI_DEBUG_SUPPORT_PROTOCOL instance.

Section 16.2.
MaxProcessorIndex Pointer to a caller-allocated UINTN in which the maximum
supported processor index is returned.
Description
The GetMaximumProcessorIndex() function returns the maximum processor index in the
output parameter MaxProcessorIndex. This value is the largest value that may be used in the
ProcessorIndex parameter for both RegisterPeriodicCallback() and
RegisterExceptionCallback(). All values between 0 and MaxProcessorIndex must
be supported by RegisterPeriodicCallback() and
RegisterExceptionCallback().
It is the responsibility of the caller to insure all parameters are correct. There is no provision for
parameter checking by GetMaximumProcessorIndex(). The implementation behavior
when an invalid parameter is passed is not defined by this specification.
