There are some minor differences between the UART om SAMD20 and SAMD21
that we need to take into account:
SYNCBUSY bit for the samd20 is located in the STATUS reg.
The samd20 does not have a SAMPR bit like the samd21.

STM32 UART driver uses a macro for clock initialization, that
is difficult to read and incompatible with needed changes to
fix STM32F0 series UART problems.
This change switches to using the full clock bus names in UART
init functions removing the macro-magic and increasing
readability.

Fix#5298
irq_is_pending function returned TXE/RXNE flag status
even if IRQ was masked, which led to enless loop

IRQ is unmasked.

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make

TEMT is Transmitter Empty bit which is set only when the full FIFO
is empty. It makes sense to poll for THRE (Transmitter Holding
Register Empty) which is set when UART can buffer new character
for transmission (there is room in FIFO). This allows using the
FIFO in full.

Per ZEP-1958, Phase 2 of adding CC3220sf LaunchXL support,
was to "deprecate the CC3200 launchxl support in Zephyr
(redundant to the CC3220)."
Effectively, the CC3220 SOC replaces the CC3200.
This patch removes the following:
* the imported CC3200 SDK
* CC3200 SOC, board, DTS files.
* adjusts other files where cc3200 was mentioned.
Also, it fixes explicit references to CC3200 in generic
CC32xx driver files.
