spi: octeon: Convert to let spi core validate transfer speed

Set master->max_speed_hz then spi core will handle checking transfer speed.
The behavior is different from current code when the speed_hz is greater than
the maximum transfer speed supported by the controller.
Unless there is other good reason, I think we had better make the behavior
consistent with what spi core does.

spi: octeon: Remove struct octeon_spi_setup usage

Current code uses struct octeon_spi_setup to store max_speed_hz, chip_select and
mode settings of current spi device.
We can always get the same settings in octeon_spi_do_transfer() by msg->spi.
So this patch removes struct octeon_spi_setup and octeon_spi_setup,
octeon_spi_cleanup functions.

The purpose of commit 1e8a52e18cfb
"spi: By default setup spi_masters with 1 chipselect and dynamics bus number"
is to avoid setting default value for bus_num and num_chipselect in spi master
drivers. So let's remove the duplicate code.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

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.
