mb/google/cyan: use shared touchpad/touchscreen interrupts 

Windows (10/11) freaks out and generates an interrupt storm
if two ACPI devices are enabled and share an interrupt, even
when only one device is actually present. To mitigate this,
mark Cyan's touchpad/touchscreen interrupts as SharedAndWake
rather than ExclusiveAndWake.

Test: build/boot Windows 10 on Relm, observe normal CPU
usage in Task Manager for System Interrupts task when
touchpad/touchscreen in use.
