Use the new function for determining the maximum simd bitwidth in
the idpf driver. An additional check is required for the AVX512DQ flag
which is not performed in the common function. Since no other drivers
require this flag, the check will remain outside of the common function.

Update the common rx path selection infrastructure to include the
feature "single queue" which is relevant for the idpf and cpfl drivers.
Replace the existing complicated logic in the idpf driver with the use
of the common function.

A minor point, but I don't particularly like this form of init for the
array. If it was all in table form, with each entry on a single line, then
it would be ok, since we could have neat columns. However, since we are
word-wrapping the lines, I'd tend towards having one element per line and
using named initializers.

To: dev; +Cc: Ciara Loftus
Use the new function for determining the maximum simd bitwidth in
the cpfl driver. An additional check is added for the AVX512DQ CPU flag
as it is not present in the common function since it is not a common
requirement for all drivers. Also, remove unused elements related to AVX
capability from the idpf_vport structure, now that neither the idpf or
cpfl drivers use them.
