mb/google/hatch/var/kohaku: Change Atmel touchscreen HID to PRP0001
This change updates the Atmel touchscreen ACPI node to use PRP0001 as
_HID to allow OF-style compatible string matching for enumeration.
Reason for this change: Atmel touchscreen driver in Linux kernel looks
for "compatible" property to decide if it is okay to attach to the
device. This check seems to be a protection against old firmware in
the field that do not have the right properties.
BUG=b:129162037
TEST=Verified that touchscreen works on Kohaku.
