The constraints API offered by TI HAL is meant to be used externally,
for example, when implementing a policy using their policy mechanism
(not used on Zephyr). The API is likely designed for systems where a
thin RTOS is used (e.g., FreeRTOS, TI-RTOS?), places where you basically
get a Kernel and a few services around, but not a system like Zephyr
where you also get, for example, a power management subsystem. This
means that it gets difficult for an RTOS like Zephyr to use such HAL
APIs while using its own constraints API. The first question is why we
allowed such kind of HAL code to be part of upstream Zephyr. It
certainly does useful things, but it is also uses a HAL infrastructure
which is hardly exportable to an RTOS like Zephyr. Part of the
Power_init() code, for example, should likely be in a clock controller
driver, where Zephyr APIs can be used.
The _solution_ that was done to workaround this case was allowing custom
full re-implementations of the constraints API. So we are basically
overwriting a functional API with custom HAL code because of poor HAL
designs. This is in general a bad design principle. If we allow this, we
can hardly offer any guarantees to the API users. For example, is
re-implemented as thread-safe? What is the API behavior then? ...
Platforms like TI that have incomplete support in Zephyr tend to leverage
to HAL code certain functions that should be proper Zephyr
drivers. Such platforms should not influence the design of APIs because
they lack solid foundations.
This patch removes the custom implementation since the HAL has been
patched so that it forwards PM state constraints to Zephyr.

TI Hal has its own constraint API that is used by its drivers. These
constraints need to be correlated with Zephyr constraints to be
constraints set in the HAL be visible on Zephyr and vice-versa.

Define SoC hooks as weak symbols so this way applications can
overwritten them defining strong symbols.
The problem is that currently SoCs are defining these interfaces as
strong symbol inhibiting the possibility of applications bring their
own implementation.

cc13x2_cc26x2 had its own power policy that was implementing the same
logic available in the default residency policy. Also, this policy was
unnecessarily setting up a timeout to wakeup the system. This is not
necessary, the power subsystem takes care of this.

The soft off power state should be supported as it is closest to what
used to be deep sleep state 1, which corresponds to the device off
state supported by hardware.

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
