So far this is the 24 MHz "HOSC" oscillator, divided down internally to 32 KHz. The F1C100 series watchdog however uses the unchanged 32 KHz "LOSC" as its only clock input, which has the same effect, but let's the binding description mismatch. Change the binding description to name the clocks more loosely, so both the LOSC and divided HOSC match the description. As the fixed clock names now make less sense, drop them from SoCs supporting just one clock input, they were not used by any DT anyway. For the newer SoCs, supporting a choice of two input clocks, we keep both the description and clock-names requirement.

Replace the compatible string with the one used by the newer generation. Verified to work with both the watchdog and reboot functionality on a LicheePi Nano. Also add the missing interrupt line and clock source, to make it binding compliant.

Describe the two controllers in the SoC .dtsi, and also add the PortC pins for SPI0, since this is where BROM looks at when trying to boot from the commonly used SPI flash. The SPI controller seems to be the same as in the H3 chips, but it lacks a separate mod clock. The manual says it's connected to AHB directly. We don't export that AHB clock directly, but can use the AHB *gate* clock as a clock source, since the SPI driver is not supposed to change the AHB frequency anyway.
