Add coda_prepare_encode() and coda_finish_encode() functions. They are called
from coda_device_run() and coda_irq_handler(), respectively, before and after
the hardware picture run. This should make the following decoder support patch
easier to read, which will add the coda_prepare/finish_decode() equivalents.

check_firmware() makes sure firmware is in a device.
It returns zero on success and error code otherwise.
Also it sets down_firmware flag to 1 if downloading occurs.
The only caller poseidon_probe() checks down_firmware flag and
returns 0 without any initialization if it is set.
That looks very strange, so the patch removes down_firmware argument
of check_firmware() and returns error code if check_firmware() fails
in poseidon_probe().
