cpu/cc2538: rtt: allow to set alarm and overflow cb independently
...
Previously the setting the alarm would overwrite the overflow callback
and vice versa.
Since we can only set one alarm in hardware, always set the alarm to the
closest event of the two.

The RTC and RTT share the same peripheral, so they can also

RTC/RTT code.

cpu/esp32: cleanup of C++ hacks
...
Since former ESP32 toolchain versions used POSIX threads, module `pthread` was required. The built-in `cxa_ctor_guards` had to be replaced since they used the `pthread_once` function for singleton objects initialization where the parameter `once` was of incompatible type with that provided by RIOT's `pthread` module. The current ESP32 toolchain version no longer uses POSIX threads. The dependency on module `pthread` as well as according C++ hacks can be removed.

cpu/sam0_common: UART: simplify init sequence
...
We don't need to read-modify-write the CTRLA register to disable
the UART.
The entire CTRLA register is re-written just a few lines below, so
we can just set it to 0 to disable the UART.
There is also no need to reset the UART since we re-write all config
registers in init.

The Atmel I2C peripheral supports arbitrary I2C frequencies.
Since the `i2c_speed_t` enum just encodes the raw frequency values,
we can just use them in the peripheral definition.
We just have to remove the switch-case block that will generate an error
for values outside of `i2c_speed_t`.
