As clearly seen on other non-MediaTek platforms, this is known to
eventually produce regressions in the future, as drivers may break
ABI and stop working with older firmware versions.
Although the firmware-name property was used in multiple MediaTek
devicetrees for the System Companion Processor (SCP) node, avoid
doing the same on MT8390 to lessen eventual ABI breakages that may
happen with a driver update to change the firmware retrieval logic
for the SCP.
This reverts commit 2f0066dae6.

On the Mediatek Genio 510-EVK and 700-EVK boards, ssusb2 controller is
one but has two ports: one is routed to the M.2 slot, the other is on
the RPi header who does support full OTG.
Since Mediatek Genio 700-EVK USB support was added, dual role mode
property is set to otg for ssusb2. This config prevents the M.2
Wifi/Bluetooth module, present on those boards and exposing Bluetooth
as an USB device to be properly detected at startup as the default role
is device.
To keep the OTG functionality and make the M.2 module be detected at
the same time, add role-switch-default-mode property set to host and
also fix the polarity of GPIO associated to the USB connector, so the
ssusb2 controller role is properly set to host when the other port is
unused.

The SCP is currently described in the Devicetree as a single-core
processor, but really it is a cluster with two cores. Describe the full
cluster but enable only core0 on the current mt8188 platforms since
that's the only one usable with the upstream firmware.

This board features multiple USB connectors:
* One Type-C connector with Power Delivery and Alt. Modes;
* One MicroUSB connector, also used for bootloader SW download;
* One USB through the RaspberryPi-compatible pins header.
Add configuration for the MTU3 controllers providing OTG support
with role switching both on the MicroUSB port, RPi pins header,
and the Type-C port found on this board.
Moreover, add the Richtek RT1715 Type-C Power Delivery Controller
which manages current source/sink, linked to the iTE IT5205 Type-C
Alternate Mode Passive Mux, handling both mode switching between
USB (up to 3.1 Gen2 10Gbps) and DisplayPort (four lanes, DP1.4,
op to 8.1Gbps) and plug orientation switching.
All USB ports reside on different controller instances, and all of
them support host or gadget and can be configured as desired at
runtime.

The MT8188 SoC has three USB controllers, and all of them are behind
the MTU3 DRD controller.
Add the missing MTU3 nodes, default disabled, for all USB controllers
and move the related XHCI nodes to be children of their MTU3 DRD to
correctly describe the SoC.
In order to retain USB functionality on all of the MT8188 and MT8390
boards, also move the vusb33 supply and enable the relevant MTU3 nodes
with special attention to the MT8188 Geralt Chromebooks, where it was
necessary to set the dr_mode of all MTU3 controllers to host to avoid
interfering with the EC performing DRD on its own.
