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 is obsolete.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.

In git, we have moved this header to uapi directory, so that it can be
installed with the headers_install target. It now has to follow
guidelines of well-formed headers usable in userspace programs.
* Update SPDX license header.
* Don't use kernel CONFIG options.

This change will add smmu mapping/unmapping support for MODS
allocated memory buffer by using kernel smmu api dma_map_sg_attrs()
and dma_unmap_sg_attrs()
1. new IOCTL MODS_ESC_IOMMU_DMA_MAP_MEMORY and
MODS_ESC_IOMMU_DMA_UNMAP_MEMORY is added to do smmu mapping/unmapping
and get smmu mapped address for MODS allocated buffers;
2. a platform device and driver is added to match mods smmu sid in dtb,
the device is used to do smmu mapping/unampping; and mods smmu devices
are added in dtb to match with the driver with smmu config
