Introducing the KTD2061/58/59/60 RGB LED drivers. The difference in
these are the address numbers on the I2C bus that the device listens to.

Due to the hardware limitation, we can only set 7 colors and the color
black (LED off) for each LED independently and not the full RGB range.

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.
