Now that the i2c_adapter migration plan changed and we are going to
keep i2c_adapter.dev, it's no longer that urgent to add a proper device
to all i2c_adapter drivers. Thus is seems resonable to degrade the
warning asking authors to migrate their driver to a debug message.

Declare the parent device of i2c_adapter devices each time we can
easily do so. It makes the i2c_adapter appear at the right place in
the device tree, rather than as a platform device.

Proposed cleanups to the i2c-amd8111 SMBus driver:
* Fold long lines.
* Add an explicit mask when writing the low byte of a word.
* Use I2C_SMBUS_BLOCK_MAX instead of hardcoding 32.
* Discard extra blank lines.
* Use boolean not instead of bitwise not for bit tests, it's clearer.
* Return -EBUSY rather than -1 on I/O resource conflict.
* Fix a race on device registration, initialization should be done
before the bus is registered.

This simple patch adds support to i2c-parport for the One For All remote
JP1 parallel port interfaces which can be found detailed at:
http://www.hifi-remote.com/jp1/hardware.shtml
These allow access to the internal configuration EEPROM on various
remote controls and there are a variety of Windows tools that make use
of this hardware. I have tested this patch with the "simple" parallel
port device and a One For All URC-7562 and confirmed that the data read
using the eeprom i2c driver matches that returned by the Windows "IR"
JP1 tool.

Driver model updates for the I2C core:
- Add new suspend(), resume(), and shutdown() methods. Use them in the
standard driver model style; document them.
- Minor doc updates to highlight zero-initialized fields in drivers, and
the driver model accessors for "clientdata".
If any i2c drivers were previously using the old suspend/resume calls
in "struct driver", they were getting warning messages ... and will
now no longer work. Other than that, this patch changes no behaviors;
and it lets I2C drivers use conventional PM and shutdown support.

The i2c-ali1563 initialization looks quite broken to me:
* If the I/O space isn't enabled, we forcibly set 3 bits in
the PCI configuration space instead of just the one enabling
the I/O space.
* After that we pretend to check if the write worked, but we
don't actually read the new value from the register.
* It's probably not a good idea to enable the I/O space if no
base address has been set.
So I propose the following changes to that part of the driver:
* Merge ali1563_enable() into ali1563_setup().
* Check the base address before the I/O space enabled bit.

rounded down when they don't fit.
