This converts the mcp23s08 driver to be able to be used with device
tree.
There is a "spi-present-mask" device tree property, that allows to
use multiple of this spi chips on the same chipselect.

Explicitly allow -1 as a legal value for the
mcp23s08_platform_data->base. This is the special value lets the
kernel choose a valid global gpio base number.

This converts the mcp23s08 driver to be able to be used with device
tree.
There is a special "mcp,chips" property, that correspond to the chips
member of the struct mcp23s08_platform_data. It can be used for
multiple mcp23s08/mc23s17 on the same spi chipselect.

I wanted to use mcp23s08 driver with a device that boots using device tree.
I modified the driver to allow the DT usage and tested with a mcp23017
which is a i2c device. I could not test the spi path, because I have no
such device.
Regards,
Lars

This converts the mcp23s08 driver to be able to be used with device
tree.
There are two properties taken, that correspond to the members of
the struct mcp23s08_platform_data, that is the base member and the
chip array member.

I wanted to use mcp23s08 driver with a device that boots using device tree.
Therefore I had to modify the driver to be able to take it's platform_data
from the device tree.
I am using a mcp23017 (I2C) device successfully with the patch booted over
device tree. I am not
