mb/google/puff: Hide LSPCON device from Windows 

Puff-based Chromeboxes use a LSPCON for HDMI 2.0 output, but no driver
exists or is needed for Windows. Use the devicetree hidden keyword to
set the ACPI status to hidden for these devices, to prevent unknown
devices from being listed in Windows Device Manager.

TEST=build/boot Win11 on google/wyvern, verify no unknown devices in
Windows Device Manager for either LSPCON device.
