soc/tegra: fuse: Extract tegra_get_platform()

This function extracts the PRE_SI_PLATFORM field from the HIDREV
register and can be used to determine which platform the kernel runs on
(silicon, simulation, ...). Note that while only Tegra194 and later
define this field, it should be safe to call this on prior generations
as well since this field should read as 0, indicating silicon.

Pull ARM/SoC driver updates from Arnd Bergmann:
"These are updates to SoC specific drivers that did not have another
subsystem maintainer tree to go through for some reason:

- Some bus and memory drivers for the MIPS P5600 based Baikal-T1 SoC
that is getting added through the MIPS tree.

- There are new soc_device identification drivers for TI K3, Qualcomm
MSM8939

- New reset controller drivers for NXP i.MX8MP, Renesas RZ/G1H, and
Hisilicon hi6220

- The SCMI firmware interface can now work across ARM SMC/HVC as a
transport.

- Mediatek platforms now use a new driver for their "MMSYS" hardware
block that controls clocks and some other aspects in behalf of the
media and gpu drivers.

- Some Tegra processors have improved power management support,
including getting woken up by the PMIC and cluster power down
during idle.

- A new v4l staging driver for Tegra is added.

- Cleanups and minor bugfixes for TI, NXP, Hisilicon, Mediatek, and
Tegra"

soc/tegra: fuse: Update the SoC revision attribute to display a name

Currently the SoC revision attribute for Tegra devices displays the
value of the enum associated with a particular revision. This is not
very useful because to obtain the actual revision you need to
use the tegra_revision enumeration to translate the value.

It is more meaningful to display a name for the revision, such as
'A01', than the enumarated value and therefore, update the revision
attribute to display a name. This change does alter the ABI, which
is unfortunate, but this is more meaningful and maintable.

soc/tegra: fuse: Add custom SoC attributes

Add a custom SoC attribute for Tegra to expose the HIDREV register
fields to userspace via the sysfs. This register provides additional
details about the type of device (eg, silicon, FPGA, etc) as well as
revision. Exposing this information is useful for identifying the
exact device revision and device type.

For Tegra devices up until Tegra186, the majorrev and minorrev fields of
the HIDREV register are used to determine the device revision and device
type. For Tegra194, the majorrev and minorrev fields only determine the
revision. Starting with Tegra194, there is an additional field,
pre_si_platform (which occupies bits 20-23), that now determines device
type. Therefore, for all Tegra devices, add a custom SoC attribute for
the majorrev and minorrev fields and for Tegra194 add an additional
attribute for the pre_si_platform field.
