arm64: dts: allwinner: add 'chassis-type' property

A new 'chassis-type' root node property has recently been approved for
the device-tree specification, in order to provide a simple way for
userspace to detect the device form factor and adjust their behavior
accordingly.

This patch fills in this property for end-user devices (such as laptops,
smartphones and tablets) based on Allwinner ARM64 processors.

arm64: dts: allwinner: teres-i: Add missing reg

The anx6345 bridge mandates that the input port is named port@0. Since
we have a unit-address, this implies that we need a reg property with
the same value, but it was found to be missing in the Teres-I device
tree. Make sure it's there.

arm64: dts: allwinner: Use the new r_intc binding

The binding of R_INTC was updated to allow specifying interrupts other
than the external NMI, since routing those interrupts through the R_INTC
driver allows using them for wakeup.

Update the device trees to use the new binding.

arm64: dts: allwinner: a64: move I2C pinctrl to dtsi

There is only one pinmuxing available for each I2C controller.

So, move pinctrl for i2c0, i2c1 from board dts files into SoC dtsi.

By moving these pinctrls the i2c1 node from Nanopi A64 just have a
status, which is disabled already so remove the entire node from it.

DLDO1 of the AXP803 PMIC. If this regulator is shut down, the HDMI
output will be blank. Therefore the simplefb driver should keep this
regulator on.

device node, if the board is capable of outputing HDMI.

arm64: allwinner: a64: allow laptops to wake up from lid

Currently all ARM kernels will have s2idle enabled if CONFIG_SUSPEND is
present. In this case if the lid is closed, systemd-logind will enter
s2idle mode by default; however there's no possible wakeup source
defined, so the system will enter a forever idle.

Add the lid itself as a wakeup source, thus the system can wakeup when
the lid is opened.
