mb/google/slippy/peppy: use shared touchpad 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 Peppy's interrupts as Shared rather than the default
of Exclusive.

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