cpu/atmega_common: Fix pm_reboot with LTO 
The reboot process for ATmegas is to enable the watchdog timer and loop until
the wdt reboots this MCU. However, this reboot will keep the wdt configuration,
so that the wdt needs to be disabled during boot. This is done in get_mcusr,
but without the attribute "used" it will be optimized out in LTO builds. This
commits adds the attribute "used" to get_mcusr.

Also simplified the backward compatibility with older ATmegas (currently not
supported by RIOT) on outdated versions of avrlibc.

70c6df9330 cpu/atmega_common/periph/uart: use TX_ISR to check TX end 
For atmega boards a TX has not actually completed until UDRn is empty
as well as the Transmit Shift Register.

To avoid resetting an UART before a TX has completed we use the TXCn
flash and ISR to set a variables that indicates TX is ongoing. This
allows not reseting the UART while there are ongoing TX pending.

This fixes an issue where part of the last byte is not shifted out
of the TX shift register causing rubish on the first TX following an
uart_init.

cpu/atmega_common/periph: Fixed bug in PCINT 
The bank index and the pin number are not necessarily identical. For all

just forgotten to update that for bank 3 as well.

cpu/atmega_common: Clean up & fix IRQ handling 
At the end of an ISR, the ATmega code was doing an `thread_yield()` instead of
 a `thread_yield_higher()`. This resulted in tests/isr_yield_higher failing.
 Fixing this saves a few lines of code, some ROM, and solves the issue.

5b6d56efd5 atmega_common: provide CPU ID for every device 
ATmega128RFA1/ATmega256RFR2 do not have a unique CPU ID.

Use the RC oscillator callibration byte as an impromptu CPU ID and rely
on bootlader constants present on all ATmega families for the remaining
bytes.

This way we can provide a faux CPU ID on all ATmega MCUs and typical hobbyists
with no access to JTAG adapters or high voltage programmer capable of writing
the user signature have a good chance that the CPU IDs of their device do not collide.

cpu/atmega_common: Add barriers to irq_*() 
To prevent reordering of accesses to the interrupt control register when link
time optimization (LTO) is enabled, memory barriers are needed. Without LTO
calls to the external functions irq_disable(), irq_restore(), irq_enable() and
irq_is_in() have the same affect as compiler barriers, as the compiler is unable
to prove that reordering of memory accesses is safe (from a single-threaded
point of view). With LTO the compiler can easily prove that reordering is safe
from a single-threaded point of view: Thus, the compiler may move memory
accesses wrapped in irq_disable(), irq_restore() across those calls.

The memory barriers will have no effect on non-LTO builds.

cpu/atmega_common: Move stdio_init() to cpu_init() 
Moving atmega_stdio_init() to cpu_init() just before periph_init() guarantees
that stdio is available to allow DEBUG() in periph_init(). This also helps to
unify the boot up process of ATmega boards and de-duplicates the stdio init from
board_init().

d9aac6a7d4 atmega_common/gpio_init: fix pull-up settings for GPIO_IN_PU 
This Patch makes gpio_init precalculate the pin mask once,
This Patch makes gpio_init of atmega_common configure the pin as an input and configure the pullup in the case of GPIO_IN_PU.
GPIO_IN_PU and GPIO_IN need to change pullup so they need to change output (this is coverd by the not touching outputs is not guaranteed statement)
(this is a special case for atmega the pull_up is configured by writing 1 to the port_register which is also the level of the output if the pin is configured to output).

This fix makes it more compliant to comments in periph/gpio.h

fixes the GPIO_LOW interrupt on the atmega platform.
It results from trying to shift GPIO_LOW. Since it is 0, it is not shiftable and will not be set correctly.
There were more issues with the other flanks too, as they are 0b01 or 0b00. If 0b11 was set as a flank before it would not be able to switch to any other mode anymore. Now the bits get cleared before the new flank will be written.
