powerpc/watchdog: Allow the Book-E driver to be compiled as a module
Register the __init and __exit functions in the PowerPC Book-E Watchdog driver as module entry/exit functions, and modify the Kconfig entry. Add a .release method for the PowerPC Book-E Watchdog driver, so that the watchdog is disabled when the driver is closed. Loosely based on original code from Jiang Yutang <b14898@freescale.com>.
