MdePkg/SmmGipDispatch2.h: SMM GpiNum meaning clarification
To support GPI number > 64, PI 1.4 clarified SMM GpiNum meaning as below:
typedef struct {
UINT64 GpiNum;
} EFI_SMM_GPI_REGISTER_CONTEXT;
Instead of the bit mask of 64 possible GPIs, GpiNum is one of 2^64 possible
GPIs that can generate an SMI. A 0 corresponds to logical GPI[00],
1 corresponds to logical GPI[1], and so on, and GpiNum of N corresponds to
GPI[N], where N can span from 0 to 2^64-1.
