H3's CCU includes some switches which disable non-secure access to some
of the more critical clock controls, such as MBUS, PLLs, and main
platform busses.
Configure them to enable non-secure access.
For now the only SoC that has this feature is the H3. For other
platforms just use a default (weak) empty function so things do
not break.

Secure Memory Touch Arbiter is the same thing as the TrustZone
Protection Controller found on A31/A31s.
Access to many peripherals on the H3 can be controlled by the SMTA,
and the settings default to secure access only.
This patch supports the new settings, and sets them to allow non-secure
access.

BUILD_BUG_* macros have been defined in several headers. It would
be nice to collect them in include/linux/bug.h like Linux.
This commit is cherry-picking useful macros from include/linux/bug.h
of Linux 4.4.
I did not import BUILD_BUG_ON_MSG() because it would not work if it
is used with include/common.h in U-Boot. I'd like to postpone it
until the root cause (the "error()" macro in include/common.h causes
the name conflict with "__attribute__((error()))") is fixed.

For compatibility clang will report some gcc version. However since we
are checking gcc versions in order to then fail to build, we should
limit these tests only to when we are using gcc and not clang.

The management data input/output (MDIO) requires open-drain,
i.MX7D TO1.0 ENET MDIO pin has no open drain, but TO1.1 supports
this feature. So to TO1.1, need to enable open drain by setting
bits GPR0[8:7] for TO1.1.
