clk: renesas: r9a09g077: Add TSU module clock

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs have a TSU
peripheral which is controlled by a module clock.

The TSU module clock is enabled in register MSTPCRD (0x30c), at bit 7,
resulting in a (0x30c - 0x300) / 4 * 100 + 7 = 307 index.

Add it to the list of module clocks.
