ArmPkg/ArmMmuLib: Explicitly cast function pointer argument

The function ArmReplaceLiveTranslationEntry () is passed as a VOID
pointer to WriteBackDataCacheRange (). This produces the following
warning on VS2019:

warning C4152: nonstandard extension, function/data pointer
conversion in expression

This change explicitly casts the argument to the formal parameter
type VOID*.

This can be reproduced with the following build command:
build -b DEBUG -a AARCH64 -t VS2019 -p ArmPkg/ArmPkg.dsc
-m ArmPkg/Library/ArmMmuLib/ArmMmuPeiLib.inf
