As the final request on a ring may hold the reference to this ring (via
retiring the last pinned context), we may find ourselves chasing a
dangling pointer on completion of the list.
A quick solution is to hold a reference to the ring itself as we retire
along it so that we only free it after we stop dereferencing it.

Slightly verbose, but does away with hand rolled shifts. Ties the field
values with the mask defining the field.
Unfortunately we have to make a local copy of FIELD_PREP() to evaluate
to a integer constant expression. But with this, we can ensure the mask
is non-zero, power of 2, fits u32, and the value fits the mask (when the
value is a constant expression).
Convert power sequencer registers as an example.

bitfield.h defines FIELD_GET() and FIELD_PREP() macros to access
bitfields using the mask alone, with no need for separate shift. Indeed,
the shift is redundant.
We define REG_FIELD_GET() and REG_FIELD_PREP() wrappers for the above,
in part to force u32 and for consistency with REG_BIT() and
REG_GENMASK(), but also as we'll need to redefine REG_FIELD_PREP() in
follow-up work to make it produce integer constant expressions.
For the most part, REG_FIELD_GET() is shorter than masking followed by
shift, and arguably has more clarity.
REG_FIELD_PREP() can get more verbose than simply shifting in place, but
it does provide masking to ensure we don't overflow the mask, something
we usually don't bother with currently.
Convert power sequencer registers as an example.
v3:
- temp variable removal (Chris)
