leds: Add SN3218 and SN3216 support to the IS31FL32XX driver

Browse Source 
Si-En Technology was acquired by ISSI in 2011, and it appears that
the IS31FL3218/IS31FL3216 are just rebranded SN3218/SN3216 devices.

Add the "si-en,sn3218" and "si-en,sn3216" compatible strings into the
IS31FL32XX driver as aliases for the issi equivalents, and update
binding documentation.

Say Y here to include support for ISSI IS31FL32XX LED controllers.
They are I2C devices with multiple constant-current channels, each
with independent 256-level PWM control.
