staging: comedi: c6xdigio: introduce c6xdigio_get_encoder_bits()

The 24-bit encoder value is read using 3-bits in the status register. The
data register is banged between each read of the status register to advance
the bits.

Introduce a helper function to handle this and remove the union encvaluetype
and struct encbitsbyte.

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.
