Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

This patch adds support for the Texas Instruments LP5030 and LP5036
I2C LED controllers. They are respectively providing up to 30 and 36
channels (i.e. 10 or 12 RGB LEDs).
In addition to the channel/color registers this LED controller provides
a per-LED brigthness register. This driver implements both LED-based and
channel-based API methods:
- led_on
- led_off
- led_get_info
- led_set_brightness
- led_set_color
- led_set_channel
- led_write_channels

The HT16K33 is a memory mapping, multifunction LED controller
driver. The controller supports up to 128 LEDs (up to 16 rows and 8
commons) and matrix key scan circuit of up to 13x3 keys.
This commit adds support for the keyscan functionality of the HT16K33.
