Update calculation for the R-Car Gen3 and RZ/G2 SoCs which have a
thermal IP block controlled by this driver. That is the:
* R-Car D3 (r8a77995)
* R-Car E2 (r8a77990)
* R-Car V3M (r8a77970)
* RZ/G2E (r8a774c0)
The calculation update is as documented in the R-Car Gen3 User's Manual,
v1.50 Nov 2018:
- When CTEMP is less than 24
T = CTEMP[5:0] * 5.5 - 72
- When CTEMP is equal to/greater than 24
T = CTEMP[5:0] * 5 - 60
This was inspired by a patch in the BSP by Van Do <van.do.xw@renesas.com>
