The flash module has status bits to indicate different thermal
conditions which are called as OTSTx. For each OTSTx status,
there is a recommended total flash current for all channels to
prevent the flash module entering into higher thermal level.
For example, the total flash current should be limited to 1000mA/500mA
respectively when the HW reaches the OTST1/OTST2 thermal level.

Changes in v3:
- Fix coding style issues to address review comments in v2.
- Link to v2: https://lore.kernel.org/r/20240513-qcom_flash_thermal_derating-v2-1-e41a07d0eb83@xxxxxxxxxxx
Changes in v2:
- Update thermal threshold level 2 register definition for mvflash_4ch_regs.
Mvflash_4ch module thermal threshold level 2 configuration register
offset is 0x78, not succeeding from thermal threshold level 1 register 0x7a.
Hence it is not appropriate to use REG_FIELD_ID to define thermal threshold
register fileds like mvflash_3ch. Update to use REG_FIELD instead.
