George Oikonomou d42b1b50e5 Allow the caller to access the entire content of CMDSTA
When sending a command to the CC13xx/CC25xx RF core, we wait for command completion by checking the LSB of CMDSTA (correctly so). However, in doing so we also zero out the 3 CMDSTA return bytes. For some commands, those bytes contain useful information (e.g. an RSSI value) and are required by the caller.

This problem manifests itself e.g. in PROP mode `channel_clear()`, whereby the caller will always see an RSSI value of 0.

This pull therefore fixes the logic in `rf_core_send_cmd()` to check for command completion by blocking on the CMDSTA result byte without zeroing out the 3 return bytes.

Fixes #1465

George Oikonomou 55b41863d5 Remove redundant function calls in CC26xx RFC code
As discussed in #1279, the current CC13xx/CC26xx rf-core code makes some unnecessary power domain-related reads. This commit removes them.

Closes #1279

George Oikonomou 8636a28248 Clear interrupt flags selectively
As discussed in #1294, every time a CC13xx/CC26xx RF interrupt fires, we clear all interrupt flags unconditionally. This may result in missed events. This patch fixes this bug by clearing only the flag that triggered the interrupt in the first place.

Fixes #1294

Billy Kozak 324d03b53c CC26xx - fully shutdown the rf-core & abort rx op
Prior to this patch, the ieee radio driver did not explicitly abort
the rx operation or power down the analog components of the radio
prior to shutting down the rf-core.

The result of this was that the rf-core continued to use a lot of
power even while "off".

This patch fixes this problem.

Billy Kozak b71353181d CC26xx - enable correct IRQ in rf_core_cmd_done_en
Fix for #1229

rf_core_cmd_done_en() was enabling the wrong irq for detecting the
completion of foreground operations. This was causing cc26xx devices
to not wake-up on time when calling lpm_sleep() from transmit().

Jonas Olsson 01e36532c2 Add support for the CC13xx CPU
This commit:

* Moves all cpu files from cpu/cc26xx to cpu/cc26xx-cc13xx
* Bumps the CC26xxware submodule to the latest TI release
* Adds CC13xxware as a submodule
* Adds support for sub-ghz mode / IEEE 802.15.4g
* Splits the driver into multiple files for clarity. We now have the following structure:
  * A common module that handles access to the RF core, interrupts etc
  * A module that takes care of BLE functionality
  * A netstack radio driver for IEEE mode (2.4GHz)
  * A netstack radio driver for PROP mode (sub-ghz - multiple bands)

This commit also adds tick suppression functionality, applicable to all chips of the CC26xx and CC13xx families. Instead waking up on every clock tick simply to increment our software counter, we now only wake up just in time to service the next scheduled etimer. ContikiMAC-triggered wakeups are unaffected.

Laslty, this commit also applies a number of minor changes:
* Addition of missing includes
* Removal of stub functions
* Removal of a woraround for a CC26xxware bug that has now been fixed
