Subject: [PATCH 2/2] unaligned: add load/store_{endian}_noalign API

The existing get/put_unaligned_{endian} API is not typed, the
arguments are in the oposite of the usual order, and the name
get/put usually implies taking/releasing a reference.

Add a typed API with the usual argument ordering and use load/store,
this API is also consistent with the aligned versions.
