Tomasz Bursztyka ea2431f32f api/spi: Reduce parameter number on transceive function
tx_bufs/tx_count and rx_bufs/rx_count can be hold in another dedicated
structure, thus reducing the number of parameters to transceive. This
permits to avoid using the stack when calling transceive.

Since we saved parameters, we can expose back the struct device pointer,
to stay consistent with other device driver APIs.

Fixes #5839

Tomasz Bursztyka 8ded57d3a2 drivers/ieee802154: Add support for Sub-GHz TI CC1200 chip
CC1200 is a sub-ghz chip supporting 6 ISM & SRD bands: 169, 433, 470,
868, 915 and 920 MHz, with features dedicated to IEEE 802.15.4(g).

Current driver enables CC1200 against actual IEEE 802.15.4 Soft-MAC. 'g'
version support in the Soft-MAC will follow later.

The chip itself is closer to a bare metal radio modem than to a usual
15.4 chip: up to the user to provide the right RF settings for the
carrier band. Such settings can be generaten through TI's SmartRF tool.

Hopefully, for channel selection, this driver will be clever enough to
compute the proper register change without any special input from the
user. This will work for all the bands supported by the chip.
