Subject: [GIT PULL] sh updates for v6.5

Hi Linus!

I am being a little late this merge window since it took me a little longer
to thoroughly review the changes which address important issues in the DMA
and IRQ code in arch/sh.

The pull request includes a patch by me to fix a compiler warning in the J2
probing code and a fix by Sergey Shtylyov to avoid using IRQ0 on SH3 and SH4
targets. Masahiro Yamada made some clean-up in the build system to address
reports by the 0day bot.

The most notable changes come from Artur Rojek who addressed a number of issues
in the DMA code, in particular a fix for the DMA channel offset calculation that
was introduced in in 7f47c7189b3e ("sh: dma: More legacy cpu dma chainsawing.")
in 2012! Together with another change to correct the number of DMA channels for
each SuperH SoC according to specification, Artur's series unbreaks the kernel
on the SH7709 SoC allowing Linux to boot on the HP Jornada 680 handheld again.

Last but not least, Guenter Roeck sent in a patch to fix a build regression that
was recently introduced in 99b619b37ae1 ("mips: provide unxlate_dev_mem_ptr() in
asm/io.h").

The following changes since commit ac9a78681b921877518763ba0e89202254349d1b:

  Linux 6.4-rc1 (2023-05-07 13:34:35 -0700)
