leds: leds-lp50xx: Allow LED 0 to be added to module bank

Browse source

commit 26fe74d598 upstream.

led_banks contains LED module number(s) that should be grouped into the
module bank. led_banks is 0-initialized.
By checking the led_banks entries for 0, un-set entries are detected.
But a 0-entry also indicates that LED module 0 should be grouped into the
module bank.

By only iterating over the available entries no check for unused entries
is required and LED module 0 can be added to bank.
