Add the Peripheral Module Clock L (PCLKL) for the RZ/T2H (R9A09G077) SoC.
PCLKL is sourced from PLL1 and runs at 62.5MHz. It is used by various
low-speed peripherals such as IIC and WDT.

Also update LAST_DT_CORE_CLK to reflect the addition of PCLKL, ensuring
correct enumeration of core clocks exposed to the DT.

i.e. will queue in renesas-clk for v6.17.
