cpu/sam0/i2c: Handle read with I2C_NOSTOP flag
...
When using the I2C_NOSTOP flag the bus should remain in control.
The current check assumes it must go to idle when reading.
This adds a condition checks if the nostop flag is active
and expects the bus status to be the owner of the bus.

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`.

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.

cpu/sam0: use GCLK ID instead of bitmask
...
To simplify board definitions and for unification between samd2x and
newer models, don't use the GCLK bitmask in board definitions.
Instead use the GCLK index and generate the bitmask when needed.
