Use the HAL event clear function to clear the RTC EVENT
instead of accessing the register directly.
This allows using an updated version of the RTC HW models
which generate level interrupts (as the real HW) and in
which if the EVEN register is not properly cleared,
the interrupts are kept high, resulting in the interrupt
handler reentering immediately after exiting.

The CIS Central uses the algorithm described in BT Core 5.4 Vol 6,
Part G, Section 2.2 to calculate the Max_PDU value for framed mode.
However, HAP needs the Max_PDU to be calculated according to "Core
enhancement for ISOAL CR" coming with the "Atlanta" update. With this
update, the fragmentation is controlled via a parameter at CIG creation.
Enabling CONFIG_BT_CTLR_CONN_ISO_AVOID_SEGMENTATION will set the
ISO_Interval to 7.5 ms for a 10 ms framed CIG, and calculate Max_PDU to
45/65 for 16/24 kHz.

In certain scenarios, the semaphore sem_ticker_api_cb may be taken
during attempt to complete a synchronous ticker operation such as start
or stop, but is never released via ull_ticker_status_give. This could
happen if ticker temporarily runs out of ticker operation slots for any
ticker client.
The consequence of ULL stuck waiting in semaphore is anything from
allocation assertions to watchdog timeouts.
This commit also sets a timeout on ull_disable calls, which relies on
the disable callback being invoked from 'done'. Invocation of 'done' is
mandatory, and code shall not allow that not to happen, but to avoid
hiding the real cause, the semaphore now has a timeout which causes
assertion in the location the issue occurred.

In the case where memq_deinit in LLL flushing ends up with the free
link being the link provided by the CIS instance, and pointed to by
lll.link_tx_free, the free counter data in the link element is
overwritten during central CIS creation.
This has the effect that when starting the next CIG, there will suddenly
be 0 links available, and controller fails assertion.
By saving- and restoring the lll.link_tx before and after CIS
configuration cache copying, the free counter is intact.
