sh: boards: Fix CEU buffer size passed to dma_declare_coherent_memory()

In all these cases, the last argument to dma_declare_coherent_memory() is
the buffer end address, but the expected value should be the size of the
reserved region.

Fixes: 39fb993 ("media: arch: sh: ap325rxa: Use new renesas-ceu camera driver")
Fixes: c2f9b05 ("media: arch: sh: ecovec: Use new renesas-ceu camera driver")
Fixes: f3590dc ("media: arch: sh: kfr2r09: Use new renesas-ceu camera driver")
Fixes: 186c446 ("media: arch: sh: migor: Use new renesas-ceu camera driver")
Fixes: 1a3c230 ("media: arch: sh: ms7724se: Use new renesas-ceu camera driver")
