Subject: [PATCH RFT v3 0/3] drivers/thermal/rcar_gen3_thermal: add Gen4 fuse support

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.

Changes since RFT v2:
* In patch 3, I mixed up the PTAT and THCODE registers. Fixed now.
  (Thanks, Shimoda-san!)
* patches are rebased to 6.4-rc1

They have been tested on R-Car H3 ES2.0 and M3-N against regressions.
Actual testing of the new fuses on Gen4 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?
A branch for testing can be found here:
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/for-thermal

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

Happy hacking,

   Wolfram
