dt-bindings: timer: arm,arch_timer: Allow dual compatible string

Since the Armv7 and Armv8 architected timers are compatible, it is valid
to expose a devicetree node with compatible string "arm,armv8-timer"
followed by "arm,armv7-timer". For example a 32-bit guest running on a
64-bit machine may look for the v7 string even though the hardware is v8.
VMMs such as QEMU and kvmtool have been using this compatible string for
some time. Clean up the compatible list a little and add the dual
option.

dt-bindings: Drop redundant minItems/maxItems

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.

dt-bindings: timer: arm,arch_timer: Add interrupt-names support

Not all platforms provide the same set of timers/interrupts, and Linux
only needs one (plus kvm/guest ones); some platforms are working around
this by using dummy fake interrupts. Implementing interrupt-names allows
the devicetree to specify an arbitrary set of available interrupts, so
the timer code can pick the right one.

This also adds the hyp-virt timer/interrupt, which was previously not
expressed in the fixed 4-interrupt form.

dt-bindings: timer: Document allwinner,erratum-unknown1 property

This arch_timer property was added in commit c950ca8c35ee
("clocksource/drivers/arch_timer: Workaround for Allwinner A64 timer instability")
but I omitted the device tree binding documentation. Now
`make dtbs_check` prints the following warning for all A64 boards:

timer: 'allwinner,erratum-unknown1' does not match any of the regexes: 'pinctrl-[0-9]+'

Resolve this by documenting the erratum property.

Fix various inconsistencies in schema indentation. Most of these are
list indentation which should be 2 spaces more than the start of the
enclosing keyword. This doesn't matter functionally, but affects running
scripts which do transforms on the schema files.

dt-bindings: Add missing 'additionalProperties: false'

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.
