The critical clock handling in __clk_core_init isn't taking the enable lock
before calling clk_core_enable, which in turns triggers the warning in the
lockdep_assert_held call in that function when lockep is enabled.
Add the calls to clk_enable_lock/unlock to make sure it doesn't happen.

This call matches clocks which have been marked as critical in DT
and sets the appropriate flag. These flags can then be used to
mark the clock core flags appropriately prior to registration.
Legacy bindings requiring this feature must add the clock-critical
property to their binding descriptions, as it is not a part of
common-clock binding.

Critical clocks are those which must not be gated, else undefined
or catastrophic failure would occur. Here we have chosen to
ensure the prepare/enable counts are correctly incremented, so as
not to confuse users with enabled clocks with no visible users.

Before adding the irq affinity based qos request to the list, if
the affinity of the interrupt changes it will trigger notify call.
This notifier call will try to update the qos request. Accessing
the qos request which is not yet added to the list leads to a
NULL pointer exception.
Avoid this race by registering the notifier after adding the
qos request.
