df90176b1f cpu/sam0_common/spi: move clk pin muxing into spi_acquire / spi_release 
When the SPI peripheral is disabled, the output lines will become HIGH-Z.
If the clk pin is not pulled HIGH or LOW, connected SPI slaves will start drawing current expectedly.

0032d35fe8 cpu/sam0_common: mitigate rounding errors of baud rate calculation 
Instead of always rounding up, the driver now rounds to the nearest integer. This reduces the absolut rounding error when setting SPI baud rates.

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.

d21dc25cfe sam0/spi: Don't re-configure SPI device when not needed 
Currently, spi_acquire() will always re-configure the SPI bus.
If the configuration did not change, this is entirely uneccecary
and makes SPI operations take longer than needed.

Instead, compare the current configuration with the new configuration
and skip the initialisation if it didn't change since the last call.

7415e0590e sam0_common: spi: use sercom_set_gen() instead of re-implementing it 
Don't repeat yourself and introduce errors in doing so.

31f88a2d0e sam0_common: periph/spi: use sercom_clk_en/dis() 
Use already existing functions to turn on / off SERCOM clocks instead
of replicating the functionality in the driver.
