Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

Tegra410 and Tegra241 deprecate the HIDREV register. The recommended
method is to use ARM SMCCC to retrieve the chip ID, major and minor
revisions, and platform information.

Prefer ARM SMCCC when the platform supports it; fall back to HIDREV
otherwise. Behavior on older Tegra SoCs that do not support ARM SMCCC
remains unchanged.

Register nvmem lookups in tegra_fuse_probe(), after the nvmem device has
been registered, since they can only be used after the nvmem device is
registered.

This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

The Jetson Nano series of modules only have 2 EMC table entries,
different from other SoC SKUs. As the EMC driver uses the SoC speedo ID
to populate the EMC OPP tables, add a new speedo ID to uniquely identify
this.

Existing code only sets CPU and GPU speedo IDs 0 and 1. The CPU DVFS
code supports 11 IDs and nouveau supports 5. This aligns with what the
downstream vendor kernel supports. Align SKUs with the downstream list.

The Tegra210 CVB tables were added in the first referenced fixes commit.
Since then, all Tegra210 SoCs have tried to scale to 1.9 GHz, when the
supported devkits are only supposed to scale to 1.5 or 1.7 GHZ.
Overclocking should not be the default state.

On Tegra platforms using ACPI, the SMCCC driver already registers the
SoC device. This makes the registration performed by the Tegra fuse
driver redundant.

When booted via ACPI, skip registering the SoC device and suppress
printing SKU information from the Tegra fuse driver, as this information
is already provided by the SMCCC driver.
