vendorcode/amd/pi/00670F00/Lib/AmdLib.c: Remove IdsErrorStop

Function IdsErrorStop() is only used within AmdLib.c function
LibAmdMsrRead(), which in turn is only used once within PspBaseLib.c and
three times inside AmdLib.c, all with well defined MSR addresses.
IdsErrorStop() is used as a trap if MSR address is 0 or 0xFFFFFFFF, which
clearly it's not. Therefor it can be safely removed from AmdLib.c.
