All the boards supported by this driver have analog inputs and all of then use the same function to handle the (*insn_read) for the subdevice. Remove the 'ai' member from the boardinfo and always initalize the analog input subdevice during the board attach. Tidy up the subdevice init a bit.

DMA support is optional in this driver. To enable it, the user passes the desired DMA channel during the board attach. A timer is then used by the driver to periodically get the analog input data from the DMA. Since the DMA support is optional, modify the init code so that it only fails if the DMA channel is unavailable or the DMA buffers can not be allocated. Don't fail just because the user passed an invalid DMA channel (only DMA channels 1 and 3 are valid). Remove the printk() noise about the DMA. Change the printk() when the request_dma() fails into a dev_err(). Move the timer initialization so it's only setup if DMA is available. It's not needed otherwise. Also, only hook up the subdevice command support functions if DMA is available. This allows removing a couple sanity checks in the command support.

As noted in the driver, a timer is always used by this driver to handle the DMA because samples could be dropped while waiting for the DMA done interrupt. Remove the irq setup code as well as the interrupt handler.

As noted in the driver, a timer is always used by this driver to handle the DMA due to buggy DMA controllers and the lack of a hardware fifo in some of the supported boards. Remove all the non-timer mode specific code.

The FB_OLPC_DCON help section is to short according to checkpatch.pl. We want more information about the controller type, its task, its video pipeline position and so on.

On resume the slave controller is reinitialized. The tegra i2c master controller disables the clock at the end of the initialiation, propably to save some power, and enables it again on each transfer. We don't do this yet and also forgot to enable the clock on resume. Fix this copy-paste error by not disabling the clock after initialization. This didn't striked us yet because suspend/resume hasn't landed in mainline yet, but will soon.
