787f9c1213 i2c: use board-specific bus numbering for '-X -b <bus>' CLI
As boards don't have their external buses labeled consistently, it was not
useful to use an abstraction.

i2c_spi_buses: add '-q' for quiet startup flag (#14969)
* [WIP] i2c_spi_buses: add '-q' for quiet startup flag

And enable for optional board sensors.

d6bb5b3b9e i2c spi buses: enforce drivers to set default SPI/I2C bus frequency
Not a lot of drivers use the global default, which is somewhat arbitrary.

83b6f6456b refactor I2CSPIInstance: store running instances in a global linked list
instead of a static per-driver array.

Reduces BSS RAM usage by a couple of 100 Bytes (linear increase with num
drivers).

Downsides:
- a bit more runtime overhead
- less isolation, locking required
- a bit more complex

e7f04109d9 i2c spi init + custom methods: use WorkItemSingleShot
Use it for custom methods as well (like reset), and run by default on the
work queue, since they typically access the bus.

f851f65f8d i2c spi: add type to I2CSPIInstance
Needed to distinguish runtime instance types of the same driver (e.g.
bmi055 accel vs gyro).
