fd9a247200 cpu/sam0_common: use generic exti_config 
Creating an `exti_config` array for a new MCU manually is tedious and error prone.
Luckiely all information is already availiable in the vendor files.

Credit for this discovery & method goes to @Sizurka

The file was generated with

```C

int main(void) {
        puts("static const int8_t exti_config[PORT_GROUPS][32] = {");

        for (unsigned port = 1; port < 5; ++port) {
                printf("#if PORT_GROUPS >= %d\n{\n", port);
                for (unsigned pin = 0; pin < 32; ++pin) {
                        printf("#ifdef PIN_P%c%02uA_EIC_EXTINT_NUM\n", '@' + port, pin);
                        printf("    PIN_P%c%02uA_EIC_EXTINT_NUM,\n", '@' + port, pin);
                        printf("#else\n    -1,\n#endif\n");
                }
                printf("},\n#endif\n\n");
        }

        puts("};");

        return 0;
}
```

No changes in generated code are expected, but this makes adding new members
of the sam0 CPU families much easier.

bd1953dd80 cpu/sam0_common: use vendor files to dispatch MCU headers

the vendor provided dispatch headers and ease the maintainance

1496149bba cpu/sam0: don't hard-code peripheral clocks 
Instead of hard-coding the peripheral clocks to CLOCK_CORECLOCK
introduce helper functions to return the frequency of the individual
GCLKs and use those for baud-rate calculations.

This requires the GCLK to be part of the peripheral's config struct.
While this is already the case for most peripherals, this also adds
it for those where it wasn't used before.

As it defaults to 0 (CLOCK_CORECLOCK) no change is to be expected.

for normal DEBUG()/printf().

01b3484ffb cpu/saml21: add definitions for low power SRAM

in backup mode.

cpu: Moved stdio_init() into cpu_init() 
- Removed stdio_init() from newlib's _init(), as this is too late in the boot
  process to allow DEBUG()ing during periph_init()

  before periph_init()

-include will throw no error if sam0_common/Makefile.features does not exist.
This may not have been intentional as none of the other sam0 implementations
do this.

849dd4cdce sam0_common: make Timer implementation common across all sam0 MCUs 
The currently supported SAM0 MCUs (samd21, saml21, saml1x) share the same
Timer peripheral, yet each of them carries it's own copy of the Timer
driver.

This introduces a new timer driver that is common for all sam0 MCUs and
uses structs for configuration instead of defines.
