Use the exclude_idle attribute of the perf events to avoid reading
PMUs of idle CPUs. The counter values are updated when CPU enters
idle and the saved value is returned when the idle CPU is queried
for that event provided the attribute is set in the perf_event.

Current code doesn't restart perf after hotplug and power collapse
which makes monitoring in low power modes difficult. This patch adds
support for the hotplug notifier events and creates a common path for
the power collapse and hotplug events.

Allocating new secure pages has very high latency. Ensure that the page
pool is completely empty before allocating new pages, splitting large order
pages as required.

Using GFP_COMP to create compound pages prevents split_pages from being
used to split an order > 0 page into order 0 pages.
Required for future changes to the system_heap allocation algorithm.

A separate heap will be used for the preallocation feature.
Also remove an associated ion_buffer private flag.

Enable clock gating of venus core, when the core is in idle
state. HLOS can do this using the Clock Gate 4.

Clients may use dma_mmap_coherent to map buffers allocated through
dma_alloc_coherent() to userspace. Support this.

Clients may have additional mappings in an iommu domain which are not
managed by arm_iommu_create_mapping. As such, it is important that
arm_iommu_create_mapping only use the iova region specified by the client.
However, the current implementation rounds the size of the region up to a
256K boundary (on arm64).

These registers need to be set everytime ARM9 is powered up.
Some may need to be set before ARM9 begins execution.
Hence setting these, before the FW is loaded by PIL.
