Staging: comedi: convert while loops to timeouts in s626.c

This patch changes a handful of while loops to timeouts to prevent
infinite looping on hardware failure. A couple such loops are in a
function (s626_debi_transfer()) which is called from critical sections,
so comedi_timeout() is unusable for them, and an iterative timeout is
used instead. For the while loops in a context where comedi_timeout() is
allowed, a new callback function, s626_send_dac_eoc(), has been defined
to evaluate the conditions that the while loops are testing.  The new
callback employs a switch statement based on a simple new enum so that
it is usable for all of the different conditions tested in while loops
in s626_send_dac().  The proper comedi_timeout() calls are then used.

staging: comedi: jr3_pci: tidy up jr3_download_firmware()

This callback function for comedi_load_firmware() first validates that
the firmware data is the correct format then it writes the data to each
subdevice.

Split the two operations out as separate functions to clarify the code.
Tidy up the new functions.

Refactor the function to reduce the indent level.

For aesthetics, rename the subdevice private data pointer from 'p'
to 'spriv'.

Rename the lacal variable used for the channel->full_scale to 'fs'
to reduce the line lengths.

Remove the setting of range[8]. The min,max values are the same as

initialized.

Remove the poll_delay_min_max() that are the same as the default.
