[PATCH v2] MinPlatformPkg/SecFspWrapperPlatformSecLib: Change TopOfTemporaryRam type

["Zhang, Shenglei" <shenglei.zhang@intel.com>]

Update the type of TopOfTemporaryRam from UINT32 to UINTN.
This change is intended to support X64 build scenarios.
The original code(line 64) may cast the overfloewed result
produced by "(TopOfTemporaryRam - sizeof (UINT32))"from
32bit to 64bit.

v2: As TopOfTemporaryRam is defined as UINTN in v2, remove
    all the related casting operations which exist in v1 patch.
