The VSPD and FCPVD nodes have overlapping register ranges, as the FCPVD
devices are mapped in the memory range usually used by the VSP LUT and
CLU, which are not present in the VSPD. Fix this by shortening the VSPD
registers range to 0x5000.
Fixes: 9f8573e38a0b ("arm64: dts: renesas: r8a7795: Add VSP instances")
Fixes: 291e0c4994d0 ("arm64: dts: r8a7795: Add support for R-Car H3 ES2.0")

Changes since v1:
- Fix H3, M3-W and M3-N in addition to V3H and D3
- Don't touch the VSPBS instance of D3 as there's no overlap
- Squash all patches together

That'd be a nightmare for the -stable maintainers -- all those commits
were made in the different time, so constant rejects are warranted.

Don't think that was a good idea in this case. Other opinions?

We have been requested ([1]) to try and group the DT changes, hence this
change. No clear rule has been set, and this might be a case where a split is
better. Olof, what would you prefer ?

We are trying to find a new balance in response to [1].
If this turns out to be a problem for -stable then we will
adjust our processes accordingly.
Applied for v4.19 as this should not have any runtime effect.
Thanks everyone.

Note that VSPBD (R-Car H3) and VSPBS (R-Car D3) also have no LUT or CLU,
so their register ranges could be shortened, too. But the're no (documented)
overlap with an FCP (or anything else).
