GPU clock may change within the period of time defined by smooth. Thus
the result of averaging load percentages within smooth window has less
meanning. New method keeps track of active GPU cycle count per time
unit, and average load is average active cycle count divided by
current GPU clock (total cycle count per time unit).

The syncpt interface APIs in the host1x-nvhost driver slightly differ
from those in the legacy nvhost driver because instead of passing the
platform device structure for the host1x device, the platform device
structure for the host1x client device is passed.
By aligning the APIs so that we pass the platform device structure for
the host1x in all implementations, we can simplify the PVA driver and
directly use the APIs in the NVIDIA display driver.
The NVIDIA display driver requires some additional syncpt interface APIs
and so implement these as well.

Exported APIs like below are defined in private header file
nvhost_syncpt_unit_interface.h
nvhost_syncpt_unit_interface_get_aperture()
nvhost_syncpt_unit_interface_get_byte_offset()
This causes linking problems if these functions are needed
by some other driver outside nvhost
Hence move these exported APIs into a new public
header in include/linux/nvhost_t194.h

Fix MODS_VIRTUAL_TO_PHYSICAL for allocations exceeding 4GB
It's unlikely for us to support such large allocations,
but if we ever did, integer overflow would truncate the
allocation offset, resulting in the incorrect PA being
returned.
This change also brings the driver up to date with
the Perforce copy and fixes the version.

For upstream dma engine slave_id in <struct dma_slave_config> is obsolete.
The Correct way to specify slave_id is
to call dma_request_chan API along with device name defined in dts node.
mods_tegra_dma: mods_tegra_dma {
compatible = "nvidia,mods_tegra_dma";
dmas = <&gpcdma 15>, <&gpcdma 16>;
dma-names = "spi1_rx", "spi2_tx";
status = "okay";
};
To keep kernel ABI compatibility,
add a new ioctl cmd MODS_ESC_DMA_REQUEST_HANDLE_2.
A new struct MODS_DMA_HANDLE_2 is used together with it.
A new function esc_mods_dma_request_channel_2 is implemented accordingly.

Summary: Previously mods stored handles for both
clocks and resets in the same list. This meant
reset signals that didn't have a corresponding
clock signal could not be toggled. This change
adds a separate list of structures to handle
resets and decouple it from the clock handling.
