Encapsulate hisi_qm_alloc_qps_node() to new interface to replace
find_zip_device(), which will fix the bug of creating QP failure
especially in multi-thread scenario.

We can configure sgl offset fields in ZIP sqe to let ZIP engine read/write
sgl data with skipped data. Hence no need to splite the sgl.

As HW SGL can be seen as a data format of QM's sqe, we merge sgl code into
qm module and rename it as hisi_qm, which reduces the number of module and
make the name less generic.
This patch also modify the interface of SGL:
- Create/free hisi_acc_sgl_pool inside.
- Let user to pass the SGE number in one SGL when creating sgl pool, which
is better than a unified module parameter for sgl module before.
- Modify zip driver according to sgl interface change.

The return valude of add_comp_head() is int, but @head_size is size_t,
which is a unsigned type.
size_t head_size;
...
if (head_size < 0) // it will never work
return -ENOMEM
Modify the type of @head_size to int, then change the type to size_t
when invoke hisi_zip_create_req() as a parameter.
