serial: sh-sci: Add support for RZ/G3L RSCI

Add support for RZ/G3L RSCI. The RSCI IP found on the RZ/G3L SoC is
similar to RZ/G3E, but it has 3 clocks (2 module clocks + 1 external
clock) instead of 6 clocks (5 module clocks + 1 external clock) on the
RZ/G3E. Both RZ/G3L and RZ/G3E have a 32-bit FIFO, but RZ/G3L has a
single TCLK with internal dividers, whereas the RZ/G3E has explicit
clocks for TCLK and its dividers. Add a new port type
RSCI_PORT_SCIF32_SINGLE_TCLK to handle this clock difference.
