6644f49e7b crypto: qat - add hook to initialize vector routing table 
Add an hook to initialize the vector routing table with the default
values before MSIx is enabled.
The new function set_msix_rttable() is called only if present in the
struct adf_hw_device_data of the device. This is to allow for QAT
devices that do not support that functionality.

590b5b7d86 treewide: kzalloc_node() -> kcalloc_node() 
The kzalloc_node() function has a 2-factor argument form, kcalloc_node(). This
patch replaces cases of:

        kzalloc_node(a * b, gfp, node)

with:
        kcalloc_node(a * b, gfp, node)

as well as handling cases of:

        kzalloc_node(a * b * c, gfp, node)

with:

        kzalloc_node(array3_size(a, b, c), gfp, node)

as it's slightly less ugly than:

        kcalloc_node(array_size(a, b), c, gfp, node)

This does, however, attempt to ignore constant size factors like:

        kzalloc_node(4 * 1024, gfp, node)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

1a72d3a6d1 crypto: qat - move isr files to qat common so that they can be reused 
Move qat_isr.c and qat_isrvf.c files to qat_common dir
so that they can be reused by all devices.
Remove adf_drv.h files because thay are not longer needed.
Move adf_dev_configure() function to qat_common so it can be reused.
Also some minor updates to common code for multidevice.
