To lower the instantaneous battery current draw of WiFi, we provide
a way to allow PowerManager to enable/disable Tx power limits.
In this CL,
we define an API in WiFi HAL, and can be referenced by Broadcom HAL.

Added API to get the supported radio combinations
of the chip. This is mainly to check if the chip is
capable of multi band simultaneous operation.
For Example in case of a chip which has two radios, where one radio is
capable of 2.4GHz 2X2 only and another radio which is capable of either
5GHz or 6GHz 2X2, number of possible radio combinations in this case
are 5 and possible combinations are
{{{2G 2X2}}, //Standalone 2G
{{5G 2X2}}, //Standalone 5G
{{6G 2X2}}, //Standalone 6G
{{2G 2X2}, {5G 2X2}}, //2G+5G DBS
{{2G 2X2}, {6G 2X2}}} //2G+6G DBS

Add ability to filter usable channnels due to coex &
concurrency limitations. Normally in standalone mode,
list of usable channels is dictated by regulatory. But
list of usable channels could be additionally limited
due to coex and also due to concurrency limitations.

Introduce a new API that can be used to query what modes (SAP,
STA, WFD Client, WFD Group Owner, TDLS, NAN) can be supported
on each channel. With this new API driver, has flexibility to
indicate to framework unambiguously what channels are usable
by each mode. Until now, framework had to derive this using
one of the NL80211_FREQUENCY_ATTR_X (NO_IR, DFS, INDOOR) which
is not sufficent to unambiguously determine allowed channels
for each interface modes.

This applies to the following types:
- audio_gain_mode_t;
- audio_flags_mask_t;
- audio_channel_representation_t;
- audio_channel_mask_t;
- audio_devices_t.
Enum types are distinct thus proper overloading on the type
is possible in C++. Also, assignments to enum types are
less prone to errors.

Enhance the API to support multiple WIFI chips.
Each WIFI chip is represented by a separate and independent
vendor HAL library providing its own function table
(wifi_hal_fn structure).
New functions added to the function table in order to
better support multiple WIFI chips:
1. In the existing hardware/interfaces/wifi implementation,
WIFI chip modes and concurrency combinations are hard-coded.
Since each WIFI chip can have its own concurrency
combinations, it is no longer possible to hard-code the
modes/combinations.
Add new function wifi_get_chip_modes for reporting
chip modes/concurrency combinations. For backward compatibility,
if the vendor HAL does not implement this function,
the previous hard-coded chip modes and concurrency combinations
will be used.
2. In the existing hardware/interfaces/wifi implementation,
when creating a new interface, it will use a fixed name
such as wlan0 or wlan1. This does not extend well to
multiple WIFI chips, as different WIFI chips may want
to use their own interface names, or the suggested interface
name may have been pre-created by another chip.
In order to better support interface creation on multiple
WIFI chips, add a function wifi_get_supported_interface_name
that allows the vendor HAL to specify its own interface
name for upcoming interface creation. If the vendor HAL returns
an interface name, it should be passed to
wifi_virtual_interface_create to create the interface
with the provided name.
3. In the existing hardware/interfaces/wifi implementation,
wifi_initialize is only called when creating the first
interface (typically when enabling WIFI). However some
chips may want to perform early initialization and provide
some functionality while WIFI is still disabled. One example
is reporting chip-global capabilities that may affect
the UI even before WIFI is enabled.
In order to support this, add a new function
wifi_early_initialize which will perform early initialization.
The function should be called as soon as possible after
loading the vendor HAL, and if it returns a failure, the vendor
HAL should not be considered usable and no WIFI chip should
be created based on it.
4. In some cases it is needed to query chip features before
creating any interfaces. For example, for trying to start
a SoftAP on the 60GHz band, it is needed to detect a chip
which supports the 60GHz band, and only if such chip was detected,
then an AP interface can be created on it.
The wifi_get_supported_feature_set function only works on
a created interface so it is not suitable for this scenario.
To support such scenarios, add a new function
wifi_get_chip_feature_set which returns a set of chip-global
features which are independent of any created interface.
