arm: imx: add initial imx8mp support ...

This adds base support for the i.MX8MP SoC. Not much to do here as this
SoC is quite similar to the i.MX8M. This adds:

- Kconfig symbols
- bootsource detection
- register base address defines
- iomux defines

scripts: imx-image: rename dcdofs to ivtofs ...

This renames the dcdofs config option in the imx-image tool to ivtofs.  dcdofs
is a misnomer. The DCD (Device Configuration Data) is only one part of the data
linked into the IVT (Image Vector Table), but the meaning of the option is
really the latter, not the former.

Arm: i.MX5: Do not disable L2 cache ...

Disabling the L2 cache is not working in imx5_init_lowlevel() because
the necessary cache maintenance operations are missing. This often
results in cache corruption in a chainloaded barebox.
Disabling the cache is unnecessary: when we come from the ROM the L2
cache is disabled anyway, so disabling it is a no-op. When we get here
in a chainloaded barebox the L2 cache is already enabled and correctly
configured. So instead of initializing it again we can take an enabled
L2 cache as a sign to skip initialization and just return from the
function.

ARM: i.MX: enable Master Identifier Unlock ...

By default the HAB locks the Master Identifier (MID) to preconfigured
values. This is not a problem if Linux is running in the secure world,
however when running a secure world operating system such as OP-TEE, the
MID configuration should be done by the secure world operating system.

This causes no regressions for systems using no secure world operating
systems, since no MID value indicates that all normal/secure world
entities can access the peripherals supporting the MID.

This adapts all files that were identifed by licensecheck

While touching these files also do some minor comment reformatting to

kbuild: remove obj-dtb-y, pbl-dtb-y, lwl-dtb-y syntax ...

The embedded DTBs are compiled by the chain of pattern rules as follows:

  %.dts -> %.dtb -> %.dtb.S -> %.dtb.o       for barebox proper
  %.dts -> %.dtb -> %.dtb.S -> %.dtb.pbl.o   for pbl

Barebox introduced {obj,pbl,lwl}-dtb-y syntax to put the intermediate
files into extra-y. The purposes of doing so were:

 [1] prevent GNU Make from deleting the intermediate files
 [2] include .*.cmd files

In contrast, Linux does not use a special syntax for embedding DTBs
into the kernel.

For example, as you see in arch/sh/boot/dts/Makefile of Linux 5.6,

   obj-y += <basename>.dtb.o

... just works.

This is because scripts/Kbuild.include specifies .SECONDARY to cater
to [1], and scripts/Makefile.build adds the intermediates to 'targets'
to deal with [2].

Barebox had already imported the same code from Linux, so you can use
obj-y instead of obj-dtb-y, like Linux.

pbl-dtb-y and lwl-dtb-y are barebox-specific cases, so I added the
%.dtb.pbl.o pattern to intermediate_targets.

Going forward, please use obj-y, pbl-y, or lwl-y.

kbuild: rename pbl object pbl-*.o to *.pbl.o ...

Currently, pbl objects are output to:

This commit changes as follows:

  <directory-path>/<basename>.pbl.o

The motivation is not only to get rid of the ugly code introduced by
commit 257abdaa36c8 ("Do not rm the path from pbl-y target"), but also
to make it easier to remove obj-dtb-y, pbl-dtb-y, lwl-dtb-y syntax in
the next commit.
