Ard Biesheuvel 66edb631f8 ArmPlatformPkg RVCT: drop dependency on GCC macro library
The RVCT .asm files include AsmMacroIoLib.h only for the definition of
LoadConstantToReg (), which makes it tedious to make change to that file
without the risk of making the RVCT assembler unhappy. So simply replace
LoadConstantToReg() with mov32, which does the right thing in all cases.
