ACPI: LPSS: drop BayTrail and Lynxpoint pinctrl HIDs

Platform devices are now created by ACPI core on device enumeration
on acpi_bus_scan() -> acpi_bus_attach() path after commit 48459340
("ACPI / scan: use platform bus type by default for _HID enumeration").
No need to create them from LPSS unless we explicitly need to set
acpi_lpss_pm_domain for them.
