From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> Add support for selecting the count clock source used by the watchdog timer. The RZ/V2H(P) SoC uses the LOCO as the count source, whereas on RZ/T2H and RZ/N2H SoCs, the count source is the peripheral clock (PCLKL). Introduce a `count_source` field in the SoC-specific data structure and refactor the clock rate selection logic accordingly. This prepares the driver for supporting the RZ/T2H and RZ/N2H SoCs, which differ in their watchdog clocking architecture from RZ/V2H(P).
