Add variables to struct madera that will be shared by the
extcon and audio codec drivers to synchronize output state
during accessory detection. Also add a mutex to protect
the DAPM pointer.

While polling for BOOT_DONE the chip could NAK a read because it is
still booting, which would terminate the regmap_read_poll_timeout()
with an error.
Instead implement a polling loop that ignores read errors so we
always poll until the chip signals boot or the loop times out.

This adds the generic core support for Cirrus Logic "Madera" class codecs.
These are complex audio codec SoCs with a variety of digital and analogue
I/O, onboard audio processing and DSPs, and other features.
These codecs are all based off a common set of hardware IP so can be
supported by a core of common code (with a few minor device-to-device
variations).
