This patch corrects two oversights relating to releasing resources
and DCB initialisation.
1. If mapping of the dcbcfg_tbl area fails: an error should be
propagated, allowing partial initialisation (probe) to be unwound.
2. Conversely, if where dcbcfg_tbl is successfully mapped: it should
be unmapped in nfp_nic_dcb_clean() which is called via various error
cleanup paths, and shutdown or removal of the PCIE device.

Add basic DCB IEEE support. This includes support for ETS, max-rate,
and DSCP to user priority mapping.
DCB may be configured using iproute2's dcb command.
Example usage:
dcb ets set dev $dev tc-tsa 0:ets 1:ets 2:ets 3:ets 4:ets 5:ets \
6:ets 7:ets tc-bw 0:0 1:80 2:0 3:0 4:0 5:0 6:20 7:0
dcb maxrate set dev $dev tc-maxrate 1:1000bit
And DCB configuration can be shown using:
dcb ets show dev $dev
dcb maxrate show dev $dev

Now that the single target build descends into sub-directories in the
same way as the normal build, these dummy Makefiles are not needed
any more.

To be able to build separate objects we need to provide
Kbuild with a Makefile in each directory.

We currently only have one app callback for vNIC creation
and destruction. This is insufficient, because some actions
have to be taken before netdev is registered, after it's
registered and after it's unregistered. Old callbacks
were really corresponding to alloc/free actions. Rename
them and add proper init/clean. Apps using representors
will be able to use new callbacks to manage lifetime of
upper devices.

Start fleshing out the apps by turning the vNIC init code to
a per-app callback. The two initial apps we have are NIC and
eBPF.
