UART pins (TX, RX, RTS, CTS) are now configured in DTS files.
RTS and CTS definitions are optional. If flow control is enabled
and RTS/CTS pins are not defined, then compiler will issue
an error message.

With the new Kconfig preprocessor (described in
https://github.com/torvalds/linux/blob/master/Documentation/kbuild/
kconfig-macro-language.txt), the syntax for expanding environment
variables is $(FOO) rather than $FOO.
$(FOO) is a general preprocessor variable expansion, which falls back to
environment variables if the variable isn't set (like in Make). It can
also be used in prompts, 'comment's, etc.
The old syntax will probably be supported forever in Kconfiglib for
backwards compatibility, but might as well make it consistent now that
people might start using the preprocessor more.

The prefixes might be a leftover from the old 'option env="..."' symbols
(which are no longer needed). Since environment variables can be
referenced directly now, there's no point in having a prefix.

Provide an implementation of gettimeofday(). This uses clock_gettime()
with the CLOCK_REALTIME parameter, which is currently unimplemented, but
will allow clients to call this function once this functionality has
been implemented.

A bootloader may leave primask or faultmask set, so clear them during
startup when we enable interrupts and switch to the main thread.
Previously we only cleared primask for architecture variants which don't
support basepri, but now we do it for all architecture variants.
Fixes a failure on mimxrt1050_evk with the latency_measure test and
shell_module sample when using an nxp internal bootloader.

_k_syscall_table is an array of function pointers and is declared as
such in C sources, this makes it an STT_OBJECT[0] in the symbol
table. But when the same symbol is declared in assembly, it is
declared to be a function, which would make the symbol an STT_FUNC.
When linking with LTO this type inconsistency results in the warning:
real-ld: Warning: type of symbol `_k_syscall_table' changed from 2 to
1 in /tmp/cc84ofK0.ltrans8.ltrans.o
To fix this warning we declare the table with GDATA instead of GTEXT,
which will change the type from 'function' to 'object'.
