Remove the PL050 PS/2 Keyboard/Mouse Interface (KMI) controller
description from the Juno DSDT as:
- PS/2 ports are now considered as legacy ports. Alternatively,
a USB Keyboard/Mouse can be connected to Juno USB ports.
- Concurrent usage of the Juno KMI and USB appear to trigger
I/O errors from the USB mass storage driver. This has proven
to be problematic as USB drivers typically cannot recover from
this issue.
