[PATCH v2 1/2] powerpc/tpm: Create linux,sml-base/size as big endian

There's code in prom_instantiate_sml() to do a "SML handover" (Stored Measurement Log) from OF to Linux, before Linux shuts down Open Firmware. This involves creating a buffer to hold the SML, and creating two device tree properties to record its base address and size. The kernel then later reads
