Platform/ARM: Correct LevelID in PLPI packages of DSDT
Juno's DSDT contains 2 PLPI packages in Clusters #0 and #1 and
_OSC method reports support for platform coordinated mode only.
According to the description of LevelID field in
ACPI 6.2 Errata A Specification #8.4.4.3,
"In a platform that only supports platform coordinated mode,
this field must be 0."
This patch fixes the above issue by changing value of LevelID
fields from 1 to 0.
