[PATCH v2 1/1] ArmPkg/ArmMmuLibb: Fix implicit cast

["PierreGondois" <pierre.gondois@arm.com>]

From: Pierre Gondois <pierre.gondois@arm.com>

While building with the following command line:
build -b DEBUG -a AARCH64 -t VS2017 -p
edk2\MdeModulePkg\MdeModulePkg.dsc

A missing cast triggers the following warning,
then triggering an error:
edk2/ArmPkg/Library/ArmMmuLib/AArch64/ArmMmuLibCore.c(652):
warning C4152: nonstandard extension, function/data pointer
conversion in expression

This patch first casts the function pointer to (UINTN),
then to (VOID*), followowing the C99 standard s6.3.2.3
"Pointer", paragraphs 5 and 6. This allows to remove the
warning.

Notes:
    v1:
     - Add (void*) cast. [Pierre]
    v2:
     - First cast to (UINTN) to conform to c99 specification. [Lazlo]
