[PATCH] i2c: Documentation fixes 

i2c documentation fixes.

>From Hideki Iwamoto:
* i2c_smbus_read_i2c_block_data is not deleted in 2.6.10. It still
  exists.
* The name which can be set to i2c_driver is up to 31 characters.

>From Jean Delvare:
* Reword the paragraph about i2c_driver.name, to reflect the "new"
  naming policy.
* Delete the out-of-date note about now gone inc_use and dec_use
  fields.

The name can be chosen freely, and may be upto 40 characters long. Please
use something descriptive here.
The name field must match the driver name, including the case. It must not
contain spaces, and may be up to 31 characters long.
Don't worry about the flags field; just put I2C_DF_NOTIFY into it. This
means that your driver will be notified when new adapters are found.

All other fields are for call-back functions which will be explained
below.
There use to be two additional fields in this structure, inc_use et dec_use,
for module usage count, but these fields were obsoleted and removed.
