Both the I2C and SPI bus code register the component immediately after they call wm8731_hw_init(), factor the code out into the the common function and rename it to just be plain wm8731_init() while we're at it since it's not just for hardware init any more. This refactoring means we need to move the function after the declaration of the component driver.
