This introduces KCONFIG_BOARD_CONFIG and KCONFIG_CPU_CONFIG variable for
boards and CPUs (including common directories) to add default
configuration files to be merged. The current approach, as it uses
Makefile.features, would include boards first, not allowing them to
override CPU configurations.
This PR removes the RX Busy detection because it doesn't seem to be
reliable enough to ensure the radio is not locked. Some radios such as
nrf802154 don't provide RX Busy detection mechanisms, so this is not
uncommon. It's intended that the MAC layer takes care of this (e.g
slots, CSMA-CA with retransmissions, etc)
`cc2538_rfcore.h` contains enums with non-prefixed single-word constants.
Those cause ugly naming conflicts down the line.
Only include the file when needed, don't include it in `cpu_conf.h` which
gets pulled in everywhere.
The RTT overflow callback is not available on all RTT implementations.
This means it is either a no-op or `rtt_set_overflow_cb()` is a no-op
or it will overwrite the alarm set with `rtt_set_alarm()`.
This adds a feature to indicate that proper overflow reporting is available.
Some periph_rtt implementations do not provide `rtt_set_counter()`. This
adds `periph_rtt_set_counter` as feature to allow testing for its
availability. The feature is provided at CPU level if periph_rtt is
provided by the board for all CPUs implementing `rtt_set_counter()`.

- Adds capabilities for each PHY mode. Converts the uint16_t caps field to an
uint32_t in order to hold all capability bits, size of the structure remains
unchanged due to alignment.
- Modifies the test application to configure the PHY mode using the shell
command. Also adds the PHY modes to the capabilities shell command.
- Updates the nrf802154 and cc2538 radio drivers to specify the PHY mode
supported.

This commit sets the correct value to the MCU_CTRL bit for the
cc2538_rf. This variable is used to detect when the radio is doing
transmission with CCA. Since this was not set to 1 when sending without
CCA, the `confirm_transmit` function returned -EAGAIN after the TX_DONE
event (which violates the HAL API).
This error was discovered using some Radio HAL riotctrl scripts by @LarsKowoll.
If the same callback function is used for multiple interfaces
(`NETDEV_INDEX_ANY`), it is necessary to also provide the index of
the interface to hand out and address.
Add periph_uart_nonblocking. Since cc2538 has a transmit FIFO write
to the FIFO first and to a tsrb buffer only when the transmit FIFO
is full.
Rely on the FIFO TXIFLSEL condition to fill up FIFO as space becomes
available.
