ec/google/chromeec: Drop `_PRS` from static devices
The `_PRS` ACPI object is not needed for static (non-configurable)
devices. For devices where `_CRS` always provides the same set of
resource settings, drop the `_PRS` object. Note that every dropped
`_PRS` object only provides one set of resource settings, which is
identical to the resource settings provided by the `_CRS` object.
