Bluetooth: Controller: tune the xtal and hard realtime radio start offsets
Bluetooth: Controller: tune the xtal and hard realtime radio start offsets

Reduce the time limit for active clock startup and increase
the CPU usage time limit before hard real-time radio
transmit/receive.

Due to isr_wrapper overhead in ARM architectures, more time
was used before hard real-time radio transmission or
reception which was detected by controller implementation
and the controller aborted the radio transactions.

This commit permits more CPU utilization by the controller
before hard real-time radio transactions start.
