Clément Léger ecef14d573 lib: sbi: implement SBI FWFT extension ...

The SBI FWFT extension defines a set of function that can be called
to control the configuration of some platform features (misaligned
trap delegation, etc). This patch implements sbi_fwft_set() and
sbi_fwft_get() as defined in the specification [1].
