[v5,0/2] leds: add ktd20xx LED driver support

v1: Initial send
v2: Remove variant 1 from source
v3: Changes requested by Andy Shevchenko added. Thanks for reviewing
  - Removing OF dependency
  - Add missing includes
  - Use device_property_read_u32() instead of fwnode_property_read_u32()
  - Use one liner function pattern <test> ? <value-true> : <value-false>
  - Remove switch case call for intensity color selection use BIT()
    instead
  - Remove not needed fwnode_handle_put() in ktd200xx_probe_dt()
    function
  - Use dev_get_drvdata() instead of i2c_get_clientdata() function call
  - Use sysfs_emit() function call
  - Use kstrtobool() function call
  - Remove not needed comma after last array element
  - Use dev_err_probe() instead of dev_error() in driver probe function
  - Do not use dev_group registration function set .dev_groups directly
    into ktd20xx_driver struct.
v4: Changes requested by Andy Shevchenko. Thanks again for your review
  - Fix Author indentation
  - Reduce logging noise
  - Use 'if' standard pattern
  - Use set_bit function to make code cleaner
  - Use meaningful jump labels
  - Updating the logging output to better match the source code
  - Remove duplicate dev pointer usage. This is not necessary as the
    information can be used directly from the client structure
  - Do not hide return value from kstrbool function
  - Do not use mutex_destroy function in devm mananged structs
v5: Changes requested by Andy Shevchenko. Thanks again for your review
so I could learn a lot about good coding style.
  - Update file header
  - Add missing comma to last array element
  - Fix spelling
  - Replace not needed atomic bit set function set_bit() with __set_bit()
  - Use more meaningful goto jump labels
  - Use return statement and not goto jump labels where possible
  - Use probe_new function
  - Use dev_dbg() function instead of dev_info() function in probe
