MAX77675 regulator driver and device tree bindings
---
Changes in v4:
- Remove the 'maxim,max77675-regulator.h' file as it is no longer used for bindings
- Eliminate unnecessary '|' characters where they are not needed
- Add and modify code to drop references that are no longer used
- Remove dead code
- Add detailed descriptions for each mode of 'maxim,en-mode'
- Rename 'maxim,latency-mode' to 'maxim,voltage-change-latency-us' for clearer meaning
- Update max77675_parse_latency_mode function to max77675_parse_voltage_change_latency accordingly
- Fix errors detected by running make dt_binding_check
- Fix incorrect indentation in the YAML file
Changes in v3:
- Removed unused variable 'value'
- Removed duplicate .list_voltage initializer
- Wrapped of_match_table with of_match_ptr() to fix build failure when CONFIG_OF is not set
- Updated driver code to match new DT binding schema
- Changed regmap_config from REGCACHE_NONE to REGCACHE_MAPLE for improved performance
- Added volatile_reg() to mark status registers as non-cacheable
- Missing explanation of `maxim,fps-slot` default value
- Updated DT binding enums to use string values (e.g., "low", "high") instead of integers
- Converted several binary properties to boolean typei
- Renamed time-based properties to use standard unit suffixes (e.g., "-sec", "-us")
- Added default values for properties
- Removed unused macros
- Renamed macros for clarity
Changes in v2:
- Fixed build error due to missing 'max77675_of_match' declaration
- Removed duplicate '.list_voltage' initialization
- Corrected value usage in regmap_update_bits call
- Added CONFIG_OF guards and used of_match_ptr()
