This patch series aims to add match data improvements for mcp23s08 driver.
This patch series is only compile tested.

v1->v2:
 * Arranged variable declaration in reverse xmas tree for patch#1.
 * Updated commit description for patch#2.
 * Dropped printing 'type' in error path for i2c_get_match_data().
 * Added similar simplification for SPI driver.

The driver has OF match table, still it uses ID lookup table for
retrieving match data. Currently the driver is working on the
assumption that a I2C device registered via OF will always match a
legacy I2C device ID. The correct approach is to have an OF device ID
table using of_device_match_data() if the devices are registered via OF.

Add struct mcp23s08_i2c_info and simplify probe() by replacing
match data 'type' with 'struct mcp23s08_i2c_info'.

While at it, replace 'dev_err()'->'dev_err_probe()' and drop printing
'type' in error path for i2c_get_match_data().

Simpilfy probe() by replacing device_get_match_data() and ID lookup for
retrieving match data by spi_get_device_match_data().

While at it, replace data type of variable type from 'int'->'unsigned int'
and declare variables following a reverse christmas tree order.
