drivers/leds/leds-pca9532.c: change driver name to be unique

This driver handles the variants pca9530-pca9533, so it chose the name
"pca953x".  However, there is a gpio driver which decided on the same
name.  As a result, those two can't be loaded at the same time.  Add a
subsystem prefix to make the driver name unique.  Device matching will not
suffer, because both are I2C drivers which match using a
i2c_device_id-table which is not altered.
