tty: serial: samsung: Add gs101 compatible and common fifoszdt_serial_drv_data
Add serial driver data for Google Tensor gs101 SoC and a common
fifoszdt_serial_drv_data that can be used by platforms that specify the
samsung,uart-fifosize DT property.
A corresponding dt-bindings patch updates the yaml to ensure
samsung,uart-fifosize is a required property.
