i2c: i2c stack can probe()
One of a series of I2C infrastructure updates to support enumeration using the standard Linux driver model. This patch updates probe() and associated hotplug/coldplug support, but not remove(). Nothing yet _uses_ it to create I2C devices, so those hotplug/coldplug mechanisms will be the only externally visible change. This patch will be an overall NOP since the I2C stack doesn't yet create clients/devices except as part of binding them to legacy drivers. Some code is moved earlier in the source code, helping group more of the per-device infrastructure in one place and simplifying handling per-device attributes. Terminology being adopted: "legacy drivers" create devices (i2c_client) themselves, while "new style" ones follow the driver model (the i2c_client is handed to the probe routine). It's an either/or thing; the two models don't mix, and drivers that try mixing them won't even be registered.
