bfb3d52a63 cpu/sam0_common: implement periph/dac 
The sam0 MCUs all have a DAC peripheral.
The DAC has a resulution of 10 or 12 bits and can have one or two
output channels.

The output pins are always hard-wired to PA2 for DAC0 and PA5 for DAC1
if it exists.

On the same54-xpro I would only get a max value of ~1V when using the
internal reference, so I configured it to use an external voltage reference.

The external reference pin is hard-wired to PA3, so you'll have to connect
that to 3.3V to get results.

5d123cbb22 cpu/sam0_common: distribute PM_NUM_MODES among siblings 
Also adapt the defines to the documentation

 - CPUs define up to 4 power modes (from zero, the lowest power mode,
   to PM_NUM_MODES-1, the highest)
 - >> there is an implicit extra idle mode (which has the number PM_NUM_MODES) <<

Previously on saml21 this would always generate pm_set(3) which is an illegal state.
Now pm_layered will correctly generate pm_set(2) for IDLE modes.

Idle power consumption dropped from 750µA to 368µA and wake-up from standby is also
possible. (Before it would just enter STANDBY again as the mode register was never
written with the illegal value.)

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.

01b3484ffb cpu/saml21: add definitions for low power SRAM 
SAML21 provides 2/4/8 kiB of Low Power SRAM that is retained
in backup mode.

This adds definitions to make that memory availiable to RIOT.
