Sometime, the radio causes a bus error.
This happens because we cast a struct and access to a member
that doesn't exists in the original struct.
This updates the driver to use the right struct to make the cast safe.

Replaces the previous approach to define bands via hardware capabilities
by the standard conforming concept of channel pages.
In the short term this allows us to correctly calculate the PHY specific
symbol rate and several parameters that directly depend from the symbol
rate and were previously not being correctly calculated for some of the
drivers whose channel pages could not be represented previously:
* We now support sub-nanosecond precision symbol rates for UWB. Rounding
errors are being minimized by switching from a divide-then-multiply
approach to a multiply-then-divide approach.
* UWB HRP: symbol rate depends on channel page specific preamble symbol
rate which again requires the pulse repetition value to be known
* Several MAC timings are being corrected based on the now correctly
calculated symbol rates, namely aTurnaroundTime, aUnitBackoffPeriod,
aBaseSuperframeDuration.
In the long term, this change unlocks such highly promising functional
areas as UWB ranging and SUN-PHY channel hopping in the SubG area (plus
of course any other PHY specific feature).

Based on the 'Technical Reference Manual' for CC13x2/CC26x2 SimpleLink
MCU family, the device contains factory pre-programmed 64-bit IEEE MAC
address for 802.15.4 radio inside two FCFG 32-bit registers:
1. MAC_15_4_0: first 32-bit of the 64-bit IEEE MAC address
2. MAC_15_4_1: last 32-bit of the 64-bit IEEE MAC address
The way current version of the driver setups the address results in
incorrect bytes order (the address is reversed):
uart:~$ ieee802154 get_ext_addr
Extended address: AF:03:B7:25:00:4B:12:00
This fixes the problem in both drivers (also in the Sub-GHz version)
which results in use of proper EUI-64 address:
uart:~$ ieee802154 get_ext_addr
Extended address: 00:12:4B:00:25:B7:03:AF
IEEE MAC address was confirmed with UniFlash, nRF Sniffer for 802.15.4
and IEEE OUI database (00:12:4B is one of registered OUI for Texas
Instruments).
To prevent confusion in future, short notice about bytes order for
'mac' field in driver's data structures was also included.

The CMD_CLEAR_RX and CMD_SET_TX_POWER commands are declared and
initialized but not used anywhere. They are therefore removed to reduce
RAM/flash footprint.

The CC13xx/CC26xx Sub-GHz driver header file defined several constants
that were not used in the driver.
Other constants could be replaced with generic constants which were
introduced in the prior commit.
This change removes and/or replaces redundant definitions.

The RSSI value in net_pkt (net_pkt_cb_ieee802154.rssi) was used
inconsistently across drivers. Some drivers did cast a signed dBm value
directly to net_pkt's unsigned byte value. Others were assigning the
negative value of the signed dBm value and again others were offsetting
and stretching the signed dBm value linearly onto the full unsigned byte
range.
This change standardizes net_pkt's rssi attribute to represent RSSI on
the RX path as an unsigned integer ranging from 0 (–174 dBm) to 254 (80
dBm) and lets 255 represent an "unknown RSSI" (IEEE 802.15.4-2020,
section 6.16.2.8). On the TX path the rssi attribute will always be
zero. Out-of-range values will be truncated to max/min values.
The change also introduces conversion functions to and from signed dBm
values and introduces these consistently to all existing call sites. The
"unknown RSSI" value is represented as INT16_MIN in this case.
In some cases drivers had to be changed to calculate dBm values from
internal hardware specific representations.
The conversion functions are fully covered by unit tests.

This is a temporary workaround for an issue in TI's RF Driver
API. A subsequent release of the SimpleLink SDK will mitigate
the need for it and it can be reverted when hal/ti receives
that update.

This change reworks the cc13xx_cc26xx IEEE 802.15.4 driver to use
the TI RF driver API that is available in modules/hal/ti.
There are a number of benefits to using TI's API including
- a stable multi-OS vendor library and API
- API compatibility with the rest of the SimpleLink SDK and SoC family
- potential multi-protocol & multi-client radio operation
(e.g. both 15.4 and BLE)
- coexistence support with other chipsets via gpio
- vetted TI RF driver resources, such as
- the radio command queue
- highly tuned / coupled RTC & RAT (RAdio Timer) API
