Subject: [PATCH] EmbeddedPkg: compiler error due to arithmetic operation on
 void pointer

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4668

This commit fixes the issue reported in the BZ4668.
The EmbeddedPkg fails to compile with a compiler error
generated due to invalid/illegal arithmetic operation
on void pointers. It has been fixed by using explicit
type conversion of the void pointer to UINTN.
