This adds the necessary device tree node on rk3566 and rk3568
to enable the I2S1 TDM audio controller.

I2S0 has not been added, as it is connected to HDMI and there is
no way to test that it's working without a functioning video
clock (read: VOP2 driver).

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 Rockchip ARM64 processors.

When writing a battery driver, I noticed that the USB voltage was ~3.7V
while running off of battery on a mainline kernel. After consulting the
schematics for the Odroid Go Advance, it appears that the BOOST
regulator is involved in the process of powering the USB host. Power
for the USB host goes from the vccsys regulator into the PMIC, then out
from the PMIC BOOST regulator into the FC9516A (which is controlled by
GPIO), which then feeds power into the USB host. I named the regulator
usb_midu because on the datasheet the pin is described as "MIDU/BOOST -
middle point of USB power supply / boost output". Making these changes
solved the USB power issue on battery and I'm now reading approximately
5v.

Note that on my board at least there is a difference in time from the
USB PHY probing and the regulators being powered on. This causes the
USB port to be undervolted for a few seconds during boot up. The
solutions to this problem are either 1) to add the proper phy-supply
on the host port, or to 2) add regulator-boot-on to the regulator. I
chose to add regulator-boot-on because there is an issue with the phy
clk that causes a warning when booting (see v1 of this patch series).
Basically the clock usb480m is a child of the usb480m_phy clock (used
by the USB PHY) and also a critical clock. Setting the phy-supply
causes this driver to be EPROBE_DEFERed until the regulator is ready,
however upon unregistering the driver to be probed later the system
cannot remove the usb480m_phy clock due to a child being marked
critical.

Changes since v2:
 - Added notes about clk problem and regulator voltage at boot.
 - Added regulator-boot-on as a workaround for the voltage at boot.
 - Removed note about fixed regulator warning, as that has been
   fixed upstream.

Changes since v1:
 - Removed phy-supply, as this generated a warning in dmesg.
