Like was done for the other non-upstream methods in
'struct ufs_hba_variant_ops', replace ->fill_prdt() with an Android
vendor hook. This is considered to be better because it avoids any
conflicts with upstream changes to 'struct ufs_hba_variant_ops'.
Note that as a side effect of this change, fill_prdt is no longer
allowed to sleep. That's fine for the only known use of this hook.

When entering cluster-wide or system-wide power mode, Exynos cpu
power management driver checks the next hrtimer events of cpu
composing the power domain to prevent unnecessary attempts to enter
the power mode. Since struct cpuidle_device has next_hrtimer, it
can be solved by passing cpuidle device as a parameter of vh.
In order to improve responsiveness, it is necessary to prevent
entering the deep idle state in boosting scenario. So, vendor
driver should be able to control the idle state.
Due to above requirements, the parameters required for idle enter
and exit different, so the vendor hook is separated into
cpu_idle_enter and cpu_idle_exit.

We have debug infrastructure built on top of preempt/irq disable/enable
events. This requires modifications to the kernel tracing code. Since
this is not feasible with GKI, we started with registering to the
existing preemptirq trace events. However the performance of wide
variety of use cases are regressed as the rate of preemptirq events
is super high and generic trace events are slow.
Since GKI allows optimized trace events via restricted trace hooks,
add the same for preemptirq event.
