[PATCH v2 1/1] ArmPkg/ArmMmuLib: Explicitly cast function pointer argument

["Michael Kubacki" <michael.kubacki@outlook.com>]

From: Michael Kubacki <michael.kubacki@microsoft.com>

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

Notes:
    V2 changes:
    
    1. Added a cast to UINTN prior to casting to VOID*.
    
       This also makes the change consistent with a very similar change
       in commit 654dc3ed852a.
