Add BasePalCallLibNull instance in MdePkg. It is useful when building IPF components in open source packages.
Use meaningful arguments defined in PalLib.h when invoking PalCall(). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4094 6f19259b-4bc3-4df7-8a09-765794883524

+ Makes a PAL procedure call.
+
+ This is a wrapper function to make a PAL procedure call. Based on the Index value,
+ this API will make static or stacked PAL call. Architected procedures may be designated
+ as required or optional. If a PAL procedure is specified as optional, a unique return
+ code of 0xFFFFFFFFFFFFFFFF is returned in the Status field of the PAL_CALL_RETURN structure.
+ This indicates that the procedure is not present in this PAL implementation. It is the
+ caller¡¯s responsibility to check for this return code after calling any optional PAL
+ procedure. No parameter checking is performed on the 4 input parameters, but there are
+ some common rules that the caller should follow when making a PAL call. Any address
+ passed to PAL as buffers for return parameters must be 8-byte aligned. Unaligned addresses
+ may cause undefined results. For those parameters defined as reserved or some fields
+ defined as reserved must be zero filled or the invalid argument return value may be
+ returned or undefined result may occur during the execution of the procedure.
+ This function is only available on IPF.
+
+ @param Index - The PAL procedure Index number.
+ @param Arg2 - The 2nd parameter for PAL procedure calls.
+ @param Arg3 - The 3rd parameter for PAL procedure calls.
+ @param Arg4 - The 4th parameter for PAL procedure calls.
+
+ @return structure returned from the PAL Call procedure, including the status and return value.
