Add support for requesting an inverted PWM pulse (active-low) when
setting up the period and pulse width of a PWM pin. This is useful
when driving external, active-low circuitry (e.g. an LED) with a PWM
signal.
All in-tree PWM drivers is updated to match the new API signature, but
no driver support for inverted PWM signals is added yet.
All in-tree PWM consumers are updated to pass a flags value of 0
(0 meaning default, which is normal PWM polarity).

The SRAM address and size are currently available as both
DT_SRAM_{BASE_ADDRESS,SIZE} and as CONFIG_SRAM_{BASE_ADDRESS,SIZE} (via
the Kconfig preprocessor).
Use the CONFIG_SRAM_* versions everywhere, and remove generation of the
DT_SRAM_* versions from gen_defines.py.
The Kconfig symbols currently depend on 'ARC || ARM || NIOS2 || X86'.
Not sure why, so I removed it.
It looks like no configuration files set CONFIG_SRAM_* at the moment, so
another option might be to use the DT_* symbols everywhere instead. Some
Kconfig.defconfig.series files add defaults to them though.
Also improve the help texts for CONFIG_SRAM_* to say that they normally
come from devicetree rather than configuration files.

The XCC toolchain may come with Clang front-end depending on
how it's built. Currently, the only SoC/board using XCC is
the intel_s1000_crb and its XCC toolchain comes with Clang
3.9.0 which has a lot better support for C99 and C++11 than
the portion based on GCC 4.2 (which does not even support
C++11). So this change attempts to use the Clang portion
instead of GCC if the Clang executable exists.

Newer XCC versions wrap unsigned int with UINT32_C(x)
in their own macros. However, the #include chain
usually does not contain UINT32_C(x). To make matters
worse, including stdint.h (where UINT32_C is defined)
in toolchain/xcc.h would cause the linker script to
contain a bunch of typedef which are invalid for
linker scripts. So define UINT32_C(x) manually.

The intention of disabling CONFIG_PRINTK is that all
invocations of it will compile to nothing, saving a lot
of runtime overhead and footprint since all the format
strings are completely dropped; instances of printk()
and related functions are no-ops.
However, some subsystems need snprintk() for string
processing, since the snprintf() implementations in even
minimal C library are too costly in text footprint or
stack usage for some applications. This processing is
required for the application to even function.
This patch continues to have disabling CONFIG_PRINTK to
cause the non snprintk functions to become no-ops, but
now we always compile the necessary bits for snprintk(),
relying on gc-sections to discard them if unused.
z_vprintk() is now unconditionally defined in the header
since it is not tied to any particular output sink and
is intended for users who know exactly what they are
doing (it's in zephyr private scope).

Add two new kconfig options USB_SELF_POWERED and USB_MAX_POWER.
These can be set by the user to change the USB configuration descriptor.
USB_MAX_POWER can be set to any value between 0 and 250, but practically
should be 50 or 250. These values are half the ammount of mA that the
device will tell the host that it needs.
USB_SELF_POWERED sets the 7th bit in bmAttributes of the USB config
descriptor. Should be set to y if the device has its own power source
other than USB.

Previously, there were two issues when attempting to use LOG_HEXDUMP_*
from C++:
First, gcc and clang in C mode both allow implicit pointer conversion
by default, but require -fpermissive, which no one should ever use, in
C++ mode. Furthermore, -Wpointer-sign, the warning emitted in C for
convertion between pointers to types of different signedness (e.g. char*
vs u8_t*) is explicitly disabled in Zephyr. Switch the various hexdump
functions to void*, which is guaranteed to work in both languages.
Second, the soon-to-be-standardized C++20 version of designated
initializers requires that the designators appear in the same order as
they are declared in the type being initialized.

In C99 the construct (T){init-list} is called a compound literal, and
is an lvalue. In C++ it is simply a cast expression to non-rvalue
type, which is a prvalue. In both languages the expression is a
temporary, but in C99 taking its address is well-defined while in C++
it is an error diagnosed as "taking address of temporary".
Headers that may be used in C++ application code must avoid invalid
expressions. Replace all uses of &(T){init-list} in headers with the
functionally equivalent but C++-legal (T[]){{init-list}}.
