pinctrl: intel: Check against matching data instead of ACPI companion
In some cases we may get a platform device that has ACPI companion which is different to the pin control described in the ACPI tables. This is primarily happens when device is instantiated by board file. In order to allow this device being enumerated, refactor intel_pinctrl_get_soc_data() to check the matching data instead of ACPI companion.
