ice: field prep conversion

Refactor ice driver to use FIELD_PREP(), which reduces lines of code
and adds clarity of intent.

This code was generated by the following coccinelle/spatch script and
then manually repaired.

Several places I changed to OR into a single variable with |= instead of
using a multi-line statement with trailing OR operators, as it
(subjectively) makes the code clearer.

A local variable vmvf_and_timeout was created and used to avoid multiple
logical ORs being __le16 converted, which shortened some lines and makes
the code cleaner.

Also clean up a couple of places where conversions were made to have the
code read more clearly/consistently.
