Subject: [PATCH 09/28] leds-lp5521/5523: add specific max_channel

 LP5521 has max 3 channels.
 On the other hand, LP5523/55231 provides up to 9 channels.
 A number of channels is used for validating platform data channel number
 while initializing LEDs.(lp55xx_init_leds)
 To support this, max_channel is configured in each driver.
