Dramatically reduce the code size for the WM8962 register defaults table
by switching to explicitly initialise only defined registers, relying on
static defaulting to zero for the overwelming bulk of the register map.

Similar treatement for the register access table will come later and will
produce a similarly dramatic code size shrink.

Rather than block the workqueue by sleeping to do the debounce use delayed
work to implement the debounce time. This should also means that we extend
the debounce time on each new bounce, potentially allowing shorter debounce
times for clean insertions.

GPIO2 and GPIO3 on the WM8962 are MFPs and need to be put into GPIO mode

Allow microphone detection on WM8962 to be performed using the interrupt

While it is a generic serial port in practice the i.MX SSI is only supported
in Linux as an audio port (the i.MX has dedicated SPI controllers and so on).
This means we don't need to disambiguate against other uses of the hardware
and so can drop the -dai suffix from the driver name which fixes merge
issues with the i.MX tree in -next.
