serial: samsung: get fifosize via device tree
UART modules on some SoCs only differ in the fifosize of each UART channel. Its useless to duplicate the drv_data structure or create a compatible name for such a change. We can get fifosize via the device tree nodes (not mandating it). Also updates the documentation.
