19735: nrf5x_common: Clear I2C periph shorts r=benpicco a=bergzand
### Contribution description
The I2C peripheral's shortcuts are used with the read and write register to automatically stop the I2C transaction or to continue with the next stage.
With simple I2C read and write bytes these shorts are not used, but are also not cleared by the function in all cases, causing it to use the shortcut configuration set by a previous function call. This patch ensures that the shorts are always set by the read and write functions
### Testing procedure
Should be possible to spot with a logic analyzer and the I2C periph test. Maybe the HIL test can also detect it :)

19729: cpu/qn908x/periph_i2c: allow internal pull-up on SCL r=maribu a=maribu
### Contribution description
Allow the board config to specify use of external or external pull-up resistor on the SCL up. Default to the internal pull-up, two weak pull ups in parallel are preferable over no pull-up.

Always enable the internal pull-up on the SCL line to always have a
functional I2C bus. This may increase power consumption where an
external pull up is present as well. But let's wait for a real world
use case where this would help to extend battery life before making
this configurable.
