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

This buffer is used to cache the values that are written to the
analog output channels. Currently it only caches the single writes
to the channels using the (*insn_write) callback. The async command
writes are not cached. The buffer is also being kzalloc'ed during
the attach of the driver to a size much larger that required.
Rename the CamelCase buffer and change it to an array in the private
data of the correct size to cache the analog output channel values.
Modify the analog output urb callback so it updates the cached values
with those used for the asynchronous command to allow readback after
the command completes.
The sanity check of the index to dac_commands[] (i.e. the 'chan' being
written) is not needed. The chanlist_len will always be less than the
number of channels.
Also, fix the dev_err() message so it uses the proper device pointer.

All the unlink helpers simply call usb_kill_urb() to cancel any pending
