thermal: renesas: rzg3e: add support for RZ/T2H and RZ/N2H
The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the
temperature calibration via SMC SIP and do not have a reset for the
TSU peripheral, and use different minimum and maximum temperature values
compared to the already supported RZ/G3E.
Although the calibration data is stored in an OTP memory, the OTP itself
is not memory-mapped, access to it is done through an OTP controller.
The OTP controller is only accessible from the secure world,
but the temperature calibration data stored in the OTP is exposed via
SMC.
Add support for retrieving the calibration data using arm_smcc_smc().
Add a compatible for RZ/T2H, RZ/N2H can use it as a fallback.

thermal: renesas: rzg3e: make calibration value retrieval per-chip
The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the
temperature calibration data via SMC SIP calls.
To prepare for supporting these SoCs, do the following changes.
Rename rzg3e_thermal_parse_dt() to rzg3e_thermal_get_syscon_trim().
Move the syscon usage out of rzg3e_thermal_get_calibration() and into
rzg3e_thermal_get_syscon_trim() and remove single-use variables from the
private state.
Place a pointer to rzg3e_thermal_get_syscon_trim() into the
chip-specific struct, and use it in the probe function to retrieve the
calibration values.
Now that syscon usage has been moved out of
rzg3e_thermal_get_calibration(), remove it and inline the calibration
validation into the probe function.
Also, reuse the TSU_CODE_MAX macro to mask the calibration values, as
GEMASK(11, 0) and 0xFFF are equivalent, and replace the hardcoded 0xFFF
with TSU_CODE_MAX in the calibration validation.

thermal/drivers/rcar_gen3: Fix mapping SoCs to generic Gen4 entry
S4 was added first so it was assumed to be the blueprint for R-Car Gen4.
It turned out now, that S4 is a special mix between Gen3 and Gen4. V4H
and V4M are the similar ones as confirmed by HW engineers.
So, rename the S4 entry to be specific instead of generic. Rename the
V4H entry to be the new generic one, so V4M will use it as well now.
