  R-Car Gen4 has the fuse registers at different locations and with
different names, but with the same purpose. So, first refactor IP core
differences into a 'info' struct, then add the fuse_read callback to it.

Patches are based on top of:

[PATCH v2 0/3] drivers/thermal/rcar_gen3_thermal: Fix device initialization
[PATCH 0/2] thermal: Add support for R-Car V4H

They have been tested on R-Car H3 ES2.0 and M3-N against regressions.
Actual testing of the new fuses on S4-8 still needs to be done because I
don't have access to such HW.

@Shimoda-san: maybe the BSP team or Test team can test these patches?

Looking forward to other review comments, too, of course.

Happy hacking,

   Wolfram

For the whole series,

Reviewed-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>

I boot tested this on V4H, but on that board the fuses where not set so 
the driver fall-back to the default values. We had a similar situation 
when we enabled fuses for Gen3. IIRC the BSP team helped out testing 
that on a board that had the fuses set.
