4b83f0d98a kbuild: turn of dtc unit address warnings by default
DTC 1.4.2 or later checks DT unit-address without reg property and
vice-versa, and generates lots of warnings.  Fixing DT files will
take for a while.  Until then, let's turn off the check unless
building with W=*.

Introduce a new helper dtc-option to check if the option is supported
in order to suppress warnings on older versions.

f32c864938 scripts/Makefile* Add SPDX-License-Identifier tag
A general best practice for SPDX is that Makefiles should have an
identifier, add these as everything else is currently covered.

15cfa32a22 kbuild: do not hide clang warnings during build with W=1
These lines originate in Linux;  it looks like Linux folks chose to
hide bunch of warnings reported by clang rather than fixing C code.

In U-boot, warnings are being fixed thanks to Jeroen's great efforts.
Let's stop suppressing clang warnings.

6419e14492 kbuild: move extra gcc checks to scripts/Makefile.extrawarn
This commit was imported from Linux Kernel:
commit a86fe353 written by me.

W=... provides extra gcc checks.

Having such code in scripts/Makefile.build results in the same flags
being added to KBUILD_CFLAGS multiple times becuase
scripts/Makefile.build is invoked every time Kbuild descends into
the subdirectories.

Since the top Makefile is already too cluttered, this commit moves
all of extra gcc check stuff to a new file scripts/Makefile.extrawarn,
which is included from the top Makefile.
