mb/google/skyrim/var/skyrim: Add VL822 USB hub
In Skyrim, USB-A port and WWAN modules are connected to the SoC USB
ports through an external hub. Update the USB configuration in the
devicetree accordingly. Enable the ACPI driver for external USB hub.
BUG=b:227761300
TEST=Build and boot to OS in Skyrim. Ensure that the hub and USB-A ports
are enumerated correctly in the output of lusub command.
