mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same memory registers. Refactor the driver to get the register addresses from the device tree and use the compatible to know the prescale factor. Calculate the watchdog setup value from the provided timeout. Don't declare it anymore as an HW_WATCHDOG, u-boot will start servicing the watchdog early enough. On mpc8xx the watchdog configuration register is also used for configuring the bus monitor. So add it as an option to the watchdog when it is mpc8xx. When watchdog is not selected, leave the configuration of the initial SYPCR from Kconfig.
