iio: pressure: dps310: take the lock once per raw read

A processed pressure read takes the lock twice: once in the raw read,
then again when dps310_calculate_pressure() trylocks to refresh the
temperature. The refresh is skipped whenever the lock is busy.

Split the raw reads into variants that expect the lock held and give each
channel a helper that takes it once for the whole sequence, so the
temperature refresh is unconditional. Buffered capture later in this
series needs the same shape.

Mark the functions that need the lock with __must_hold() rather than a
comment, and include cleanup.h, which ACQUIRE() needs and was coming in
transitively.
