Quite a lot of activity in SPI this cycle, almost all of it in drivers
with a few minor improvements and tweaks in the core.
- Updates to pxa2xx to support Intel Broxton and multiple chip selects.
- Support for big endian in the bcm63xx driver.
- Multiple slave support for the mt8173
- New driver for the auxiliary SPI controller in bcm2835 SoCs.
- Support for Layerscale SoCs in the Freescale DSPI driver.

An spi_driver does not need to set an owner, it will be populated by the
driver core.

The Documentation/devicetree/bindings/iio/dac/ad7303.txt DT binding doc
lists "adi,ad7303" as a compatible string but the corresponding driver
does not have an OF match table. Add the table to the driver so the SPI
core can do an OF style match.

Introduce an enum to specify whether the attribute is separate or
shared.
Factor out the bitmap handling for loop into a separate function.
Tidy up error handling and add a NULL assignment to squish a false
positive warning from GCC.
Change ext_info shared type from boolean to enum and update in all
drivers.
