Trying to keep the number of kernels we compile for these
platforms small and 4.16 is likely to be EOLed soon anyway.

The kernel configs are the 4.16.x configs run through
a 'make defconfig && make oldconfig' cycle.

Note, we skip 4.14.45 because 4.14.46 only has 3 patches
in it which unbreak 'perf' compilation.

The s390x build VM we have access to is quite slow. Dropping
the 4.15.x kernel, which soon will be EOLed anyway, to
save some time.

The kernel config is based on the 4.15.x kernel config
run through 'make defconfig && make oldconfig' and then
tweaked a little by hand.

There are too many kernels to compile and arm64 takes a bit
too long to compile even on a beefy arm64 server.

- Disable all network device driver apart from Mellanox, which
is the only support NIC on s390x
- Disable Fusion MPT
- Disable DAX/NVMEM/NVME
- Disable USB

While this now has some duplication, it is clearer as to which
kernels are compiled for each architecture.

Update building process to add s390 support.
The patch serial-forbid-8250-on-s390.patch has been added to disable
8250 serial for s390.
The patch is available upstream https://patchwork.kernel.org/patch/10106437/
but it is not backported.

Also remove the 4.4 patch which should have been removed by
231cead2cc ("kernel: Update to 4.15.4/4.14.20/4.9.82/4.4.116")

We may soon get another arch, so wanted to set the template
for having per arch list of kernels to compile.
While at it also drop the 4.4.x kernel for arm64. We never really
tested it and folks should be on 4.9 or 4.14 anyway. I'll leave
4.4.x for x86 for now as it might be useful to test for regressions.

In order to cut the number of kernels we build, remove the debug
kernel for the now non-default 4.9.x series.
Also remove the -rt debug kernel. Users who need it can build
it themselves with 'make EXTRA=-rt DEBUG=-dbg build_4.14.x'
