leds: pca955x: Convert enum->pointer for data in the match tables

Convert enum->pointer for data in the match tables, so that
device_get_match_data() can do match against OF/ACPI/I2C tables, once i2c
bus type match support added to it.

Replace enum->struct *pca955x_chipdefs for data in the match table.
Simplify the probe() by replacing device_get_match_data() and ID lookup
for retrieving data by i2c_get_match_data().

While at it, add const definition to pca955x_chipdefs[].
