When sched_enable_thread_grouping is turned on, the scheduler needs
to ensure that any pre-existing children of a task get added to the
co-location group. Upon removal from the co-location group, however,
the scheduler does not check for the thread grouping flag because
userspace cannot ensure correct behavior. Therefore as a
precautionary measure to avoid memory leaks the scheduler has to
forcefully remove children from the group regardless of the flag
setting.
While at it, also make group management a lot simpler. Without these
simplifications, we can end up in extremely complicated locking scenarios
where ensuring the correct order to avoid deadlocks is near impossible.

The regulator name for the PMICOBALT BOB regulators uses the
prefix "pmcobalt_bob". Change this to "pmicobalt_bob" so that
the regulator name correctly reflects which PMIC the regulator
is found on.

Add the votable name in the first line of the debug output. This helps
in understanding which voter the output is for.

The default value of CPE FLL threshold register needs to be updated
to 0x20 as per the hardware specification. Change fixes this by
adding this register to the codec register defaults.

Enable PMM_TCXO_CLK before swith to cxo. Also, add
debug logs of reading WCSS_SR_PMM_SR_MSB register
multiple times to check whether ref clock is shut off
or not when xo disable command failed.

Memory core and memory peripheral blocks should remain
on upon host bus suspend otherwise XHCI controller
fails to respond to XHCI commands upon host bus resume.
These memory blocks will be turned off only upon stopping
host mode or vbus off in device mode.

Integer overflow check is invalid when ULONG_MAX is used,
as ULONG_MAX has typeof 'unsigned long', while areq->assoclen,
q_req->crytlen, and qreq.ivsize are 'unsigned int'. Make change
to use UINT_MAX instead of ULONG_MAX.
