ec7727077b native: nrf52 changes to HAL to support running on simulated HW
Conditionally compiled changes to the NRF52 HAL so it can
run on simulated HW on the native port.
(HW models are not included in this commit)

All changes are under ifdefs and therefore will not have any
effect on normal builds

PA/LNA feature being not default enabled, keeping the PPI

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.

74cd8d852e Bluetooth: controller: Use single PPI channel for AA capture
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.

c3adc7b0c7 Bluetooth: controller: PHY Update Procedure
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.
