arm: dts: am33xx: Sync dts with Linux 4.20.0

This patch synchronizes the am33xx SoC specific files with those from
Linux 4.20.0. Hence all board maintainers of am33xx based boards are
on the cc list.
The main purpose of this patch is to prevent further diverging of the
dts files from U-Boot and those from Linux. It aims to set the stage
for the synchronization of board specific dts files. Example: I'm the
maintainer of the PDU001 board: once this patch is applied successfully
I will make changes to the board specific dts file in Linux only and
then post a patch with a copy of this exact dts file to U-Boot. This
will make U-Boot and Linux remain in sync.
The stumbling block of https://patchwork.ozlabs.org/patch/943627 was
removed by the patch https://patchwork.ozlabs.org/patch/962428 from
Lokesh Vutla (many thanks!). This omap-serial driver allows using the
Linux am33xx.dtsi file in U-Boot.
Other changes to dts and dtsi files made by this patch are mainly to
prevent _new_ warnings during the build process. Especially the warning
at pinmux@800 stating 'unnecessary #address-cells/#size-cells without
"ranges" or child "reg"' was not removed. This warning is a good example
showing the benefit of the synchronization: if it needs to be fixed it
will be fixed in Linux and ported back to U-Boot.
Buildman reports all 46 am33xx SoC based boards to build fine, with
warnings of course. Nevertheless this patch should be tested thoroughly
on as many boards as possible to prevent any collateral damage.

no such mechanism exists for the pre-reloc stage of the full U-Boot.

With the default defconfig for the RK3399-Q7 (which filter the

caused a pause during startup of the full U-Boot stage that lasted for
almost 10s (due to the CPU not having been clocked up yet).

This reintroduces the guard from commit f4fcba5c5baa ("clk: Allow
clock defaults to be set also during re-reloc state") and extends it
to only apply outside of a TPL/SPL build: i.e. clk_set_defaults will

by del_mtd_device() and complain loudly when there's nothing we can

Notice that the first pattern has dashes throughout, while the second has
dashes throughout except just before the target architecture which has an
underscore.

The "dash throughout" versions from kernel.org are:

8.1.0, 6.4.0, 5.5.0, 4.9.4, 4.8.5, 4.6.1

buildman/toolchain.py: fix toolchain directory

The hexagon toolchain (4.6.1) from kernel.org, for example, was packaged in
a way that is different from most toolchains. The first entry when unpacking
most toolchain tarballs is:

gcc-<version>-nolib/<targetarch>-<system>

e.g.:

gcc-8.1.0-nolibc/aarch64-linux/

The first entry of the hexagon toolchain, however, is:

gcc-4.6.1-nolibc/

This causes the buildman logic in toolchain.py::ScanPath() to not be able to
find the "*gcc" executable since it looks in gcc-4.6.1-nolib/{.|bin|usr/bin}
instead of gcc-4.6.1/hexagon-linux/{.|bin|usr/bin}. Therefore when buildman
tries to download a set of toolchains that includes hexagon, the script fails.

This update takes the second line of the tarball unpacking (which works for
all the toolchains I've tested from kernel.org) and parses it to take the
first two elements, separated by '/'. It makes this logic a bit more robust.
