Subject: [PATCH v4 03/17] mfd: madera: Add common support for Cirrus Logic Madera codecs
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).

Changes since V3:
- Fixed missing Kconfig dependency on PINCTRL
- commented purpose of madera_name_from_type(), call it earlier
in probe and store the string in a member of struct madera
- removed the madera_get_num_micbias and madera_get_num_childbias
exported functions and introduced static madera_set_micbias_info
to init this information in members of struct madera
- adjusted the commenting on the switch that adds the LDO1 child driver
- squashed the two switches on hardware ID into one (we used to re-read
the HWID after reset hence the second switch on it but as we don't do
that now the two switches can be combined)
- pre-init ret to remove the else ret = 0 in madera_get_reset_gpio
Changes not made to V3 review comments:
- left the dev_dbg messages in runtime_suspend and runtime_resume,
they are only _dbg and they've been useful in the past for debugging
