This reverts commit fe2731211e.
By default the commit muxes the pin to a GPIO upon a request_irq()
call from the client driver. This is incorrect as the client driver
could have muxed the pin already for a different purpose. Hence,
revert this default behavior to not enforce this on the clients.

Instead of flushing whole buffer use partial cache maintenance apis
to flush only for length user passed. Introducing offset based flush,
when buffers have partial or full overlap, avoiding flush for overlap.

Add the initial support required to share memory buffers
between VMs. This driver exposes an interface to userspace
clients to request memory to be allocated from another VM,
and added to the current VM. The VMs communicate with each
other via the use of the hypervisor message queues, as well
as utilize various facilities offered by the Haven resource
manager to manage memory that is transferred from one VM
to another.

Add a check to mark only cached buffers as iocoherent.
We can't enable io-coherency for uncached buffers because
of situations where hardware might snoop the cpu caches
which can have stale data.This happens primarily due to the
limitations of dma caching APIs available on arm64.

When set_rate is called on unprepared clocks new vdd_level
requirement is not cached, which leads to incorrect votes
when later clk_prepare is called. Clocks may not be prepared
when clk pre change rate is called for set_rate change request,
thus cache vdd level and only apply vote during clk prepare.

SMMU hw voting did not tie these 2 clocks. Although these
clocks are default enabled on boot, SW needs to explicitly
make sure to keep them always enabled to keep smmu access.
These clks will automatically turn on/off along with
CX_GDSC so no power hit.

proceed further.
