leds: rgb: leds-ktd202x: I2C ID tables for KTD2026 and 2027

Browse Source 
Add an i2c_device_id id_table to match manually instantiated
(non device-tree / ACPI instantiated) KTD202x controllers as
found on some x86 boards.

This table shows the maximum support LED channel for KTD2026
(three LEDs) and KTD-2027 (4 LEDs).
