f79cc88e4e spi: octeon: Convert to use bits_per_word_mask
Since commit 543bb25 "spi: add ability to validate xfer->bits_per_word in SPI
core", the driver can set bits_per_word_mask for the master then the SPI core
will reject transfers that attempt to use an unsupported bits_per_word value.
So we can remove octeon_spi_validate_bpw() and let SPI core handle the checking.

fe81109b6d spi: octeon: Remove empty octeon_spi_nop_transfer_hardware function
Both prepare_transfer_hardware and unprepare_transfer_hardware callbacks are
optional, so we don't need to implement an empty function for them.

fd4a319bc9 spi: Remove HOTPLUG section attributes
CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Bill Pemberton has done most of the legwork on this series. I've used
his script to purge the attributes from the drivers/gpio tree.
