drivers/periph/timer: Use uint32_t for frequency 
For all currently supported platforms `unsigned long` is 32 bit in width. But
better use `uint32_t` to be safe.

310eb4970c cpu/sam0_common: GPIO: use tamper detection to wake from Deep Sleep 
On samd5x only the RTC can wake the CPU from Deep Sleep (pm modes 0 & 1).
The external interrupt controller is disabled, but we can use the tamper
detection of the RTC.

If an gpio interrupt is configured on one of the five tamper detect pins,
those can be used to wake the CPU from Deep Sleep / Hibernate.

sam0_common: Use Single-cycle I/O Port for GPIO when available 
The Cortex-m0 based ATSAM devices can use the Single-cycle I/O Port for
GPIO. This commit modifies the gpio_t type to use this port when
available. It is mapped back to the peripheral memory space for
configuration access.  When it is not available, the _port_iobus() and
_port() functions behave identical, which is the case for the samd51.

39d71ac671 cpu/sam0_common: GPIO: ignore interrupts when interrupts are disabled 
If we disable an external interrupt, GPIO events that would generate an interrupt will still set the interrupt flag.
That means once we enable the interrupt again, a stale interrupt will be triggered.

This is surprising and probably not what the user wants, unfortunately the API documentation is not very clear about what to expect.
There is however no way to drop those intermediate interrupts with the current API.

Ignoring the events that occurred while the GPIO interrupt were disabled is probably the right (and expected) thing to.

83a56ae666 cpu/sam0_common: merge RTC & RTT implementation 
The RTC and RTT share the same peripheral, so they can also
share the same code.

This is needed to integrate the Tamper Detection into common
RTC/RTT code.

e1f84de6c5 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.

7269dc4e3a cpu/sam0_common: i2c: allow arbitrary I2C frequencies 
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`.
