Vinayak Kariappa Chettimada 57e49b1f03 Bluetooth: controller: Refactor BT_CTLR_ADV_INDICATION feature
Refactor BT_CTLR_ADV_INDICATION feature by moving the
implementation closer to the implementation that is closing
the advertisement event so that in the future new members
can be added as necessary (example, advertised channels).

Vinayak Kariappa Chettimada bb84be2c5c Bluetooth: controller: Fix ticker to use u32_t ticks_slot
ticker timespace reservation can range up to 10.24 seconds,
needing 19-bits to represent in 32KHz clock units. Hence,
fix controller implementation to use u32_t to store ticks
slot values.

Without this fix, the controller is asserting in scan_adv
sample when using continuous scanning with 2 second interval
and window.

Vinayak Kariappa Chettimada ad7c9d3d76 Bluetooth: controller: Improved continuous scanning
Refactored the high frequency clock preparation advanced
feature to improve radio utilization during continuous
scanning.

The inter-event timespace value now considers the reserved
timespace while determining if the high frequency clock
will be retained. This reduces the preparation time, hence
increased radio use inside scan window.
