References to the WM5102 tables need to be guarded.

Mark Brown cfe775ce62 mfd: Treat arizona register read errors as non-fatal during resume
We're testing for a specific value and while SPI does not detect I/O
errors I2C can.

Mark Brown 59db96913c mfd: Move arizona digital core supply management to the regulator API
Rather than open coding the enable GPIO control in the MFD core use the
API to push the management on to the regulator driver. The immediate
advantage is slight for most systems but this will in future allow device
configurations where an external regulator is used for DCVDD.

Mark Brown 3cc7298694 mfd: arizona: Core driver
Several forthcoming Wolfson devices are based on a common platform
known as Arizona allowing a great deal of reuse of driver code. This
patch adds core support for these devices.

In order to handle systems which do not use the generic clock API a
simple wrapper for the 32kHz clock domain in the devices is provided.
Once the generic clock API is widely available this code will be moved
over to use that.

For simplicity some WM5102 specific code is included in the core driver,
the effort involved in splitting the device out isn't worth it.
