net/ionic: support vdev for embedded applications

Add support for running DPDK applications directly on AMD Pensando
embedded HW. The platform exposes the device BARs through UIO. The
UIO code in the common/ionic library walks the sysfs filesystem
to identify the relevant BARs and map them into process memory.

The SoCs are named 'Capri' and 'Elba'.

The vdev device interface code is located in ionic_dev_vdev.c.

Some datapath operations are #ifdef-ed out to save on resources when
running in embedded mode.

Some control path operations are skipped by the ionic_is_embedded()
helper function.

Before ringing the doorbell, use an ARM 'dsb st' barrier. The normal
barrier inside rte_write64() is insufficient on these devices due to
a chip errata.

net/ionic: add optimized non-scattered Rx/Tx

The code is very similar, but the simple case can skip a few branches
in the hot path. This improves PPS when 10KB mbufs are used.

S/G is enabled on the Rx side by offload DEV_RX_OFFLOAD_SCATTER.
S/G is enabled on the Tx side by offload DEV_TX_OFFLOAD_MULTI_SEGS.

S/G is automatically enabled on the Rx side if the provided mbufs are
too small to hold the maximum possible frame.

To enable S/G in testpmd, add these args:
--rx-offloads=0x2000 --tx-offloads=0x8000

mk: ignore missing field initializers warning

Three warnings are commonly disabled in DPDK with make and meson:
* address-of-packed-member
always disabled
* missing-field-initializers
disabled with meson
disabled with make + clang or make + gcc < 4.7
disabled with make + gcc <= 5 for test files and event drivers
* packed-not-aligned
disabled with meson

This change is removing exceptions for missing-field-initializers.
As it is always disabled, some redundant configs are cleaned up.

Now the situation is:
* address-of-packed-member
always disabled
* missing-field-initializers
always disabled
* packed-not-aligned
disabled with meson

It could alternatively be decided to disable missing-field-initializers
only for old gcc (< 6).

The warning packed-not-aligned is not modified in this change.

net/ionic: ignore missing field initializers warning

The compiler warning is:
from .../drivers/net/ionic/ionic_dev.c:7:
.../drivers/net/ionic/ionic_if.h:202:5: note: ‘rsvd’ declared here
u8 rsvd[62];
^

This has been observed with gcc 4.8.5, newer 9+ compiler are not giving
this warning.

Warning is a reminder to the user that there are some fields in the
struct not initialized with the default value.
But the C standard clarifies that in that case the field value will be
zero and code is aware of this behavior, so no initializing to a default
value is intentional and it is safe to ignore this compiler warning.

Adding '-Wno-missing-field-initializers' compiler flag to disable the
warning.
