superio/smsc/sch5545: Drop `_PRS` for 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.

In addition, drop `IGNORE_IASL_MISSING_DEPENDENCY` from the only
mainboard using the SCH5545 code, `dell/snb_ivb_workstations`.
