RPMB FS driver may allocates a temporary buffer of size the one provided
by userland caller. These may be big buffer of dozens of kbytes and may
exhaust the heap capacities. Change the implementation to use a 4kByte
temporary buffer to update RPMB data instead of an allocated buffer of
the object target size. RPMB FAT entry data is updated by chunks of the
temporary buffer size, and RPMB FAT meta data is updated afterwards as
prior this change.
