Fix conditional compilation in nRF5 radio interface so that
when Coded PHY feature is not selected then it does not use
the PPIs required for supporting the feature.
This will allow pwm_nrf5_sw driver to use PPI channels 14 to
19 and support 3 PWM channels. Without the Coded PHY feature
disabled, only PPI 14, 15, 18 and 19 are available for PWM.

This commit contributes the implementation of the sw-switch for
tIFS in nRF5 Radio using the EVENT_TIMER instead of a dedicated
TIMER instance. A Kconfig configuration is added so the user can
select whether to use the EVENT_TIMER for the tIFS switch or use
a dedicated TIMER instance.

PA/LNA feature being not default enabled, keeping the PPI
indices used for this feature at the higher indices would
allow use of these PPI indices by other drivers, for
instance the nRF5 software PWM driver.
Software PWM driver provides 3 PWM pins/channels using upto
6 PPI channels. If BLE controler where to use 0-13, then
14-19 PPI indices can be used by the PWM driver.

Always use S8 Rx Chain Delay instead of the actual Rx-ed

value.

Earlier design captured AA twice in the first Rx in a slave
connection event and retained one of the capture until end
of event to calculate drift.
Design updated to use single capture of AA and save the
first AA capture in a slave connection event in RAM instead.
This frees up a PPI channel in the controller design.

The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.
Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

Added support for Bluetooth v5.0 PHY Update Procedure in the
Controller.
Asymmetric PHY connections do not work for now due to the
Radio mode not being setup in time in the ISR during tIFS
period and the Radio already ramping up in the cached
previous Radio mode to meet tIFS deadline.
Subsequent commits will add this feature, by either double
buffering the mode in software or using fast radio ramp up
which gives enough time in the ISR to change the mode.
