Convert each file at I2C subsystem, renaming them to .rst and
adding to the driver-api book.

A few drivers open code the handling of suspended adapters. It could be
handled by the core, though, to ensure generic handling. This patch adds
the flag and accessor functions. The usage of these helpers is optional,
though. See the kerneldoc in this patch. Using the new flag, we now
reject further transfers if the adapter is already marked suspended.

Documentation/i2c/fault-codes illustrates EINVAL error code
as follows:
"One example would be a driver trying an SMBus Block Write
with block size outside the range of 1-32 bytes."
However, the actual implementation of i2c subsystem truncates
data length to be 32 bytes.
Hence this example cannot happen anymore, and since it's obsolete,
let's simply remove it from Documentation/i2c/fault-codes.

Create Documentation/i2c/fault-codes to help standardize
fault/error code usage in the I2C stack. It turns out that
returning -1 (-EPERM) for everything was not at all helpful.
