net: dsa: yt921x: Refactor long register helpers

Browse source

Dealing long registers with u64 is good, until you realize there are
longer 96-bit registers.

Refactor reg64 helpers to use u32 arrays instead of u64 values, in
preparation for 96-bit registers. We do not keep the separate u64
version for reg64 to avoid duplicated wrappers, although it looks better
when dealing with reg64 *only*.

Helpers for reg96 should be added when they are actually used to avoid
function unused warnings.
