From: Roberto Sassu <roberto.sassu@huawei.com>

Changelog:

v4:
- Replace sg_init_table()/sg_set_buf() with sg_init_one() (suggested by
Eric)

v3:

v2:
- Add patch by Herbert to take only the needed bytes for a MPI from the
scatterlist
- Use only one scatterlist for signature and digest (suggested by Eric)
- Rename key variable to buf (suggested by Eric)
- Rename key_max_len variable to buf_len
- Use size_t for the buf_len variable instead of u32

v1:
- Unconditionally copy the signature and digest to the buffer to keep the
code simple (suggested by Eric)
