In the past there have been hard to recreate issues where XIVE changes
cause qemu crashes due to multi-socket interrupts such as in [1].
Add a functional test explicitly to test whether remote interrupts work.
The test can also work as additional boot test for multi-socket boot,
initrd boot test, as well as a check for e1000e to be working in powernv,
though that's not a target goal, and are additional benefits.
From docs/system/devices/net.rst:
In order to check that the user mode network is working, you can ping
the address 10.0.2.2 and verify that you got an address in the range
10.0.2.x from the QEMU virtual DHCP server.
Hence use 10.0.2.2 with ping.

Currently pnv-spi-seeprom-test was hardcoded to test the 4th chip in
pnv_chips (power10 as of now).
This requires ensuring to update the index when removing/adding entries
in pnv_chips, such as when Power8E or Power11 gets removed/added in
future commits.
Iterate over all the chips instead, similar to other tests in
pnv-xscom-test.c and pnv-host-i2c-test.c, but skip older chips, since
TYPE_PNV_SPI only exists from Power10 onwards, hence skip older machines
Tests all the pnv_chips similar to other qtests

Previously the machines/chips tested by qtest was till Power10, update
the tests to also test PowerNV11 and Power11 PNV Chip
Since if-else-if ladder was common pattern to get machine type,
implement pnv_get_machine_type so new processor cases can be implemented
in one location in pnv_get_machine_type
While at it, also add g_autofree to allocation by g_strdup_printf in
modified tests

The default powernv machine has been recently changed to powernv11,
though fadump functional test used powernv10
Change it to use default 'powernv' machine for the tests instead of
being fixed to powernv10

Power8E and Power8NVL were deprecated since QEMU 10.1, with
commit 264a604e7163 ("target/ppc: Deprecate Power8E and Power8NVL")
As Power8E chip is removed in future commits, remove the use of Power8E
chip for use with the none machine test, and replace with Power11 for
ppc64 test coverage for the test

Power8E and Power8NVL were deprecated since QEMU 10.1, with
commit 264a604e7163 ("target/ppc: Deprecate Power8E and Power8NVL")
Accordingly, remove usage of 8E and 8NVL chips from powernv, as it's old
and unmaintained now.

Power8E and Power8NVL were deprecated since QEMU 10.1, with
commit 264a604e7163 ("target/ppc: Deprecate Power8E and Power8NVL")
Remove the corresponding 8E and 8NVL CPU cores from spapr/pseries
Also, with no use of 8E and 8NVL, in powernv chips or spapr cores,
remove the CPU definitions for the cores
