raw/ifpga: fix free function mismatch in interrupt config

The raw ifpga driver redefines malloc to be opae_malloc
and free to be opae_free; which is a bad idea.

This leads to case where interrupt efd array is allocated with calloc()
and then passed to rte_free.
The workaround is to allocate the array with rte_calloc() instead.

drivers: convert to internal control threads

Calls to rte_ctrl_thread_create() are replaced with
rte_thread_create_internal_control().
Other pthread-related functions are replaced with the rte_thread API.
Only pthread_cancel() has no replacement.

The mlx5 vDPA control threads were real-time threads
with an affinity on the core specified by the devarg "event_core".
As there is no heavy performance requirement,
these threads are converted into real control threads.

Some threads in dlb2 and mlx5 are not control threads
because they are designed to run on some specific cores.
It would be interesting to rework them in future.

Previous FPGA platform like Intel PAC N3000 and N5000, FME DFL (Device
Feature List) starts from BAR0 by default, port DFL location is indicated
in PORTn_OFFSET register in FME. In OFS implementation, FME DFL and port
DFL location can be defined individually in PCIe VSEC (Vendor Specific
Extended Capabilities). In this patch, DFL definition is searched in VSEC,
the legacy DFL is used only when DFL VSEC is not present.

In original DFL enumeration process, AFU is expected to locate in port DFL,
but this is not the case in OFS implementation. In this patch, enumeration
can search AFU in any PF/VF which has no FME and port.

There is an API rte_pmd_ifpga_cleanup provided by ifpga driver to

The interrupts are unregistered in ifpga_rawdev_destroy instead of
ifpga_rawdev_close function, so rte_pmd_ifpga_cleanup cannot free
interrupt resource as expected.

To fix such issue, interrupt unregistration is moved from
ifpga_rawdev_destroy to ifpga_rawdev_close function. The change of
function call of ifpga_rawdev_destroy is as below.
